Impact modification of poly(caprolactam) by copolymerization with a low molecular weight polybutadiene

摘要: Caprolactam and a reactive, low molecular weight polybutadiene were polymerized in an autoclave, followed by post-condensation the solid state. The rubber concentration was varied (0–30 wt%). morphology of reaction products studied transmission electron microscopy. In materials with 10 20 wt% polybutadiene, large spherical polybutadiene-rich domains nylon sub-inclusions observed. 30 product shown to have co-continuous structure. moduli decrease rapidly content only material highest had high notched Izod impact strength.
