the effect of caprolactam on tensile properties and morphology of recycled high density polyethylene ethylene vinyl acetate rhdpe eva blends
Advanced Materials Research, 2016Co-Authors: A R H Fatimah, A.g. Supri, Z FiruzAbstract:This paper describes tensile properties, and morphology analysis of different composition of RHDPE and EVA blends were studied. The main goals are to describe the effect of Caprolactam as compatibilizer used to improve the compatibility between RHDPE and EVA. The RHDPE/EVA blends were prepared at 160°C and the rotor speed of 50rpm in an internal mixer. The tensile strength for RHDPE/EVA blends increased, while adding Caprolactam by 6phr in the blend formulation significantly improved the tensile properties. The SEM micrograph show a better interfacial adhesion between RHDPE and EVA phases for RHDEP/EVA/Caprolactam blends than RHDPE/EVA blends.

chicken feather fibers recycled high density polyethylene composites the effect of e caprolactam
Journal of Thermoplastic Composite Materials, 2015Co-Authors: A.g. Supri, Mim Yazid, Emy A Aizat, M MasturinaAbstract:The effects of e-caprolactam on tensile properties, morphology, thermal degradation, and swelling behavior of recycled high-density polyethylene–chicken feather fiber composites (r-HDPE/CFF) were studied. The r-HDPE/CFF composites were prepared using Brabender Plasticorder at 160°C and a rotor speed of 50 r min−1 for 6 min. The r-HDPE/CFF/e-caprolactam composites exhibit higher tensile strength, modulus of elasticity, and final decomposition temperature, but lower mass swell percentage and elongation at break than r-HDPE/CFF composites. Scanning electron microscopic morphology showed that the CFF was more widely dispersed in the r-HDPE matrix with the addition of e-caprolactam as a coupling agent. It was also found that the addition of e-caprolactam offers better thermal stability in r-HDPE/CFF/caprolactam composites than r-HDPE/CFF composites.

Tensile Properties, Swelling Behavior, and Morphology Analysis of Recycled High Density Polyethylene / Natural Rubber / Chicken Feather Fibers (R-HDPE / NR / CFF) Composites: The Effects of Caprolactam
Advanced Materials Research, 2013Co-Authors: A.g. Supri, Mohammed IzzuddeenAbstract:The effect of caprolactam as a coupling agent on the tensile properties, swelling behavior and morphology analysis of recycled high density polyethylene/ natural rubber/ chicken feather fiber (R-HDPE/ NR/ CFF) composites was studied. The R-HDPE/NR/CFF composites with and without caprolactam were prepared using Brabender Plasticorder at 160°C and rotor speed of 50 rpm. The results indicated that R-HDPE/NR/CFF with caprolactam showed higher value of tensile strength but lower elongation at break and mass swell percentage than R-HDPE/NR/CFF composites. SEM morphology showed that the addition of caprolactam improved the fiber matrix-interfacial adhesion and good dispersion of the fiber in the R-HDPE/NR blends.

molecular weight distributions of industrially produced poly ɛ Caprolactams by gel permeation chromatography
Journal of Chromatographic Science, 2007Co-Authors: Elena Mateos, Vicente L Cebolla, Luis Membrado, Elena Piera, Miguel Angel CaballeroAbstract:Gel permeation chromatography with differential refractometry is used to obtain molecular weight distributions (MWD) of poly-(e-Caprolactams). Elution is carried out using an m-cresol-chlorobenzene mixture (50:50, v/v) at 50°C. MW values are obtained by a Hamielec-based calibration method, using broad-MWD poly-(e-caprolactam) standards with the same chemical nature and similar MWD to the samples. Relative errors for the number-average MW (M n ) using this calibration method range from 0.4% (in the low polyamide MW range) to 20% (in the high polyamide MW range). These values are much lower than those obtained from narrow-MWD polystyrene calibration, which range from 39% to 78%. Similar values have been obtained for the other usual average MW parameters. The ability to obtain repeatability parameters for a given confidence interval and the utilization of statistical criteria for chromatogram rejection allow this method to be used in quality control for MWD of poly-(e-Caprolactams). Thus, production variables are related to polyamide-6 behavior in its ulterior treatment. Typical relative standard deviation percentages (for n = 6) of a polyamide sample range from 1.9% (for Mn) to 3.3% (forM z+1 ).

2007Co-Authors: Elena Mateos, Vicente L Cebolla, Luis Membrado, Elena Piera, Miguel Angel CaballeroAbstract:Gel permeation chromatography with differential refractometry is used to obtain molecular weight distributions (MWD) of poly-(e-Caprolactams). Elution is carried out using an m-cresol‐ chlorobenzene mixture (50:50, v/v) at 5 0°C. MW values are obtained by a Hamielec-based calibration method, using broadMWD poly-(e-caprolactam) standards with the same chemical nature and similar MWD to the samp les. Relative errors for the number-average MW (M n) using this calibration method range from 0.4% (in the low polyamide MW range) to 20% (in the high polyamide MW range).
