摘要

正

Three polycaprolactam samples modified by 0.05—0.50% polyphenylquinoxaline（PPQ）by weight were prepared.Their structure and mechanical properties were characterized by FT-IR

SEM

density

tensile

impact

DTAand visco-elastic method

PPQ induced the formation of "crystal grains" distributed evenly over nylon spherulites in modified samples

which were observed for the first time

and strengthened modified samples. Modified nylons had higher crystallinities

higher T

more nearly perfect spherulites than MC nylon itself

and showed typical reinforcing effect on mechanical properties.
