effect of supramolecular hydrogen bonded network on the properties of maleated ethylene propylene diene rubber maleated high density polyethylene blend based thermoplastic elastomer
Materials Letters, 2006Co-Authors: Young-wook Chang, Joy K. MishraAbstract:Abstract A thermoplastic elastomer having supramolecular hydrogen bonded network was prepared by the melt mixing of maleated ethylene propylene diene rubber and maleated high density polyethylene in presence of 3-amino-1,2,4-triazole (ATA), which acts as a coupling agent. The hydrogen bonded network formation in the blend system enhanced the physical properties of the blend. The storage modulus and glass transition temperature of the elastomer–plastic blend containing ATA was found to be increased as compared to the blend without ATA. It was observed that polyblends containing ATA exhibit a Rubbery Plateau above the melting temperature of the maleated high density polyethylene. Reprocessability study confirmed the thermoplastic elastomeric nature of the polyblend system.

Application of the synthetic polymer approach to the glass transition of fruit leathers
Journal of Food Engineering, 2008Co-Authors: P. J. Torley, P. Shrinivas, Stefan Kasapis, J. Boer, Bhesh Bhandari, B. JiangAbstract:Abstract A commercial fruit leather was analysed in an effort to document the application of the synthetic polymer approach to its vitrification properties. Techniques employed were dynamic mechanical thermal analysis on tension and modulated differential scanning calorimetry. The temperature and frequency dependence of Young’s modulus were utilized in the construction of composite curves of viscoelasticity that identified the Rubbery Plateau, glass transition region and glassy state. The painstaking investigation of viscoelasticity supported by the combined framework of WLF/free-volume theory was successful in identifying the mechanical T g of the partially vitreous material at subzero temperatures. That was contrasted with the corresponding value obtained using calorimetry, and the nature of the discrepancy between the two estimates of T g was discussed.

polymer solvent interaction observed in Rubbery Plateau modulus
Polymer International, 1998Co-Authors: N Nakajima, J P VarkeyAbstract:The conventional wisdom is that concentration dependence of the Rubbery Plateau modulus of polymer solutions is independent of the material. However, in industrial practice, sometimes a small addition of miscible liquid lowers the modulus significantly whilst at other times it hardly affects it. This work examines an example of the former case (nitrile rubber–plasticizer systems) and one of the latter (acrylic rubber–plasticizer systems). Two possible explanations are offered for the observed behaviour. One is a possible contribution of a polar association to the Plateau modulus: when a solvent breaks the association it gives the former case and when it does not, it gives the latter. The other explanation is a possible contraction of polymer coils from unperturbed size giving the former case, and an expansion giving the latter. Changes of less than a few percent of the coil-radius are sufficient to explain the above behaviour © 1998 SCI.
