IMPACT-RESISTANT POLYAMIDE COMPOSITION AND PROCESS FOR PRODUCTION OF SAME

Title:

IMPACT-RESISTANT POLYAMIDE COMPOSITION AND PROCESS FOR PRODUCTION OF SAME

Document Type and Number:

WIPO Patent Application WO/2011/162333

Kind Code:

A1

Abstract:

Provided are: an impact-resistant polyamide composition which exhibits improved toughness and improved impact strength and which can be easily polymerized in-situ in a molding stage; and a novel process for the production of the same. The novel process comprises initiating the anionic polymerization of ε- caprolactam in the presence of (A) an anionic polymerization catalyst, (B) an anionic polymerization activator, (C) 2.0 to 30wt% (relative to the ε-caprolactam) of an N,N-disubstituted vinylbenzylamine, and (D) a radical polymerization initiator, and subjecting the resulting system to reaction under conditions comprising a reaction temperature of the reaction system of 120 to 180°C and a reaction time of 10 seconds to 120 minutes. Since the radical polymerization in the process is conducted without hindering the anionic polymerization, an alloyed polyamide composed of both polylcaprolactam and poly(N,N-disubstituted vinylbenzylamine) can be obtained.
