Abstract

SynopsisTo improve the impact resistance of polyamide 6, we tried to form polymer alloy by the polymerization of ε-caprolactam in the presence of prepolymers consisting of flexible chain with isocyanate group at the both terminals. In this system, polyamide 6 and the block copolymer having flexible chain in as the middle segment were generated to form polymer alloy automatically. IZOD impact tests revealed that the polymer alloy was improved in impact strength compared with polyamide 6. Further, we evaluated the impact energy absorption of the glass fiber-reinforced composite produced with the polymer alloy as the matrix resin. As the results, the impact energy absorption was 1.4 times higher than that with polyamide 6 matrix.
