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

, 1988
Caprolactam and a reactive, low molecular weight polybutadiene were polymerized in an autoclave, followed by post-condensation in the solid state. The rubber concentration was varied (0–30 wt%).
