Preparation of N-66/g-ABS Blends by Chemically Grafting Long Chain Compounds on the Butadiene Region of ABS, using a Novel UV Irradiation Technique

Abstract

Acrylonitrile butadiene styrene (ABS) was grafted using long chain molecules like oleic acid and dodecylamine. Grafting took place at the butadiene region of ABS. Grafted ABS (g-ABS) polymers were characterized using FTIR and blended with nylon-66 in various proportions. Physical, chemical, mechanical and thermal properties of the blends were analyzed. A physical blending technique was followed between nylon-66 and ABS and all properties were compared with the modified blends. SEM reveals that miscibility characteristics were found to be enhanced, as the modification of ABS makes it more compatible with nylon-66.
