Title:
POLYPHASE STRUCTURE AND PROCESS FOR ITS PRODUCTION
Document Type and Number:
WIPO Patent Application WO/1987/007285
Kind Code:
A1
Abstract:
The polyphase structure is prepared by kneeding: (A) 30 to 60 wt % of aliphatic polyamide; (B) 35 to 55 wt % of polyphenylene ether; and (c) 5 to 20 wt % of A-B-A' type diene block copolymer (wherein A and A' each represents the same or different polymerized vinylaromatic hydrocarbon block, and B represents polymerized conjugated diene block), with (A)+(B)+(C) of 100 wt %, and the aliphatic polyamide (A) forming a matrix phase, the polyphenylene ether (B) forming a primary dispersed phase in the matrix phase, and the diene block copolymer (C) forming a secondary dispersed phase in the primary dispersed phase. This polyphase structure gives moldings excellent in impact resistance, rigidity, and heat resistance, and can be used as automobile parts, mechanical parts, and electric and electronic components.
