Abstract

Abstract: Chain-extension of polyamide6 (PA6) was carried out by reacting with 2,2'-(1,3-phenylene)bis(2-oxazoline) (MPBO) in melt. The optical chain-extension was found when the loading of MPBO was 2.0 % at 240 ℃. After chain-extension, the number-average molecular weight of PA6 increased from 1.4×104 to 2.5×104, the tensile strength, elongation at break, and intrinsic viscosity increased, the melt flow index dropped. However, crystallinity and crystallization temperature were decreased.

Key words: polyamide 6, chain extension reaction, mechanical property, 2, 2'-(1, 3-phenylene)bis(2-oxazoline)
