Male partner involvement and assistance in female condom use.
The European Journal of Contraception & Reproductive Health Care, 2008Co-Authors: Mags Beksinska, Jenni Smit, Zonke Mabude, Gowri Vijayakumar, Jabu LindaAbstract:Objective To investigate how males assist their partners in using the female condom.Methods A multi-site, randomized, cross-over trial was conducted to test the performance and acceptability of the Reality® female condom compared to a prototype similar in design and appearance but made of Synthetic Latex (FC2). In this study women were asked about male partner assistance in FC use.Results Partner assistance in FC use was similar across FC type. Of the women who returned for the first follow-up visit (n = 233), just over a third (35.2%) reported that the male partner assisted in the insertion compared to 26.4% of the 201 women who returned for the second visit. In most cases where the partner assisted, the device was inserted using the inner ring, as recommended in the instructions for use. A small number (6%) mentioned that partners assisted in removal.Conclusion Men have a role to play in the use of the female condom and are willing to assist their partners in using it.

Short-term acceptability of the Reality polyurethane female condom and a Synthetic Latex prototype: a randomized crossover trial among South African women.
Contraception, 2006Co-Authors: Jenni Smit, Mags Beksinska, Gowri Vijayakumar, Zonke MabudeAbstract:Abstract Purpose This multisite, randomized, crossover trial comparing the acceptability of the Reality® female condom (FC1), with a new Synthetic Latex prototype (FC2) of similar design and appearance to FC1, was conducted in Durban, South Africa. Methods In total, 276 women were enrolled and 1910 FC1 condoms and 1881 FC2 condoms were used by 218 and 216 women, respectively. Results Overall experience of use was reported as good for over half the participants with both condom types (FC1=50.9%, FC2=55.1%). Similar acceptability issues were reported in like proportions for FC1 and FC2, with features such as the lubricant (FC1=36.7%, FC2=37.0%) and the material (FC1=36.2%, FC2=29.2%) most commonly viewed positively for both condom types. Negative aspects commonly reported for both female condoms were the lubricant (FC1=30.3%, FC2=31.5%) and the appearance (FC1=29.8%, FC2=34.0%). Preference for FC1 was 29.5% and was slightly higher for FC2 (36.6%). Some women felt that there was no real difference between the two devices (33.8%). Conclusion The acceptability of FC1 and FC2 was comparable, and women who find FC1 acceptable to use should also find FC2 acceptable.

Performance of the Reality® polyurethane female condom and a Synthetic Latex prototype: a randomized crossover trial among South African women
Contraception, 2005Co-Authors: Mags Beksinska, Jenni Smit, Zonke Mabude, Gowri Vijayakumar, Carol JoanisAbstract:Abstract Objective This multisite, randomized, crossover trial comparing the performance of the Reality® female condom (FC1) with a new Synthetic Latex prototype (FC2) was conducted in Durban, South Africa. Method In total, 276 women were enrolled and 201 women completed the study. Altogether, 1910 FC1 condoms and 1881 FC2 condoms were used. Results Total breakage was 0.73% in FC1 and 0.85% in FC2 (95% confidence interval, −0.64 to 0.87). The number of clinical breakages (those that could result in a pregnancy or sexually transmitted infection) was similar for each condom type (FC1, n=9; FC2, n=8). Incorrect penetration (penis between condom and vaginal wall) was 1.26% and 0.64% for FC1 and FC2, respectively. Outer ring displacements (outer ring pushed into the vagina partially or fully) were comparable for both condoms (FC1, 3.14%; FC2, 2.98%). Slippage (condom came out of the vagina) was rare and reported in 0.37% or less of devices used. Total clinical failure was 5.24% in FC1 and 4.3% in FC2. Conclusion The FC1 and FC2 performed comparably within this trial.

Reinforcing Latex coatings with reactive Latex particles
Progress in Organic Coatings, 2014Co-Authors: Andriy Popadyuk, Nadiya Popadyuk, Volodymyr Samaryk, Ihor Tarnavchyk, Ananiy Kohut, Stanislav Voronov, Andriy VoronovAbstract:A new approach to the crosslinking and filling Synthetic Latex coatings has been developed. Peroxi-dized monodisperse polystyrene Latex particles have been used as a crosslinker and, simultaneously,as a filler of polymer coatings based on acrylic and styrene-butadiene Latexes. The synthesis of reac-tive (peroxidized) Latex particles was carried out using the emulsion polymerization of styrene in thepresence of the polymer inisurf, the initiator-surfactant, a copolymer of a peroxide monomer, N-[(tert-butylperoxy)methyl]acrylamide with maleic anhydride. The reactive Latex particles were employed tocrosslink polymer coatings from Synthetic acrylic and styrene-butadiene Latexes.The hardness and solvent resistance of the coatings based on both Latexes increase with an increasingamount of the reactive Latex filler in the formulation. The crosslinked coatings, based on styrene-butadiene exhibited better characteristics in terms of hardness and solvent stability. The properties ofLatex-crosslinked coatings depend on reaction temperature and the amount of the crosslinker, peroxi-dized reactive polystyrene Latex particles.

Synthetic latices: general principles of production
Polymer Latices, 1997Co-Authors: D. C. BlackleyAbstract:This chapter is concerned with the general principles relating to the production of those colloidal systems which have become known as Synthetic latices. The subsequent chapter will discuss individual types of Synthetic Latex. The main concern in the subsequent chapter will, of course, be those Synthetic latices which have attained industrial importance to a greater or lesser degree. However, note will also be taken of certain other interesting types which so far have either been of very limited specialist application interest, or have remained of essentially academic interest only.

Synthetic latices: individual types
Polymer Latices, 1997Co-Authors: D. C. BlackleyAbstract:The previous chapter has dealt with the general principles which underlie the production of Synthetic latices by emulsion polymerization. This chapter reviews the individual types of Synthetic Latex. The concern is exclusively with aqueous Synthetic latices. Non-aqueous Synthetic latices are also used industrially; they are produced by emulsion/dispersion polymerization in non-aqueous media. However, aqueous Synthetic latices far exceed non-aqueous Synthetic latices as regards multiplicity and industrial importance. The main concern in this chapter is, of course, with Synthetic latices which have attained industrial importance to a greater or lesser extent. However, brief reference is also made to certain other interesting types which so far have either been of very limited specialist applicational interest only, or remained of essentially academic interest. Almost all the Synthetic latices of industrial importance are produced by free-radical addition polymerizations of olefinically-unsaturated monomers in aqueous dispersion media.
