Title:
POLYPHENYLENE ETHER AS WELL AS RESIN COMPOSITION AND MOLDING THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/049743
Kind Code:
A1
Abstract:
[Problem] To provide a polyphenylene ether of superior color tone and fluidity and a polyphenylene ether-containing resin composition of superior heat resistance, mechanical properties, etc. [Solution] This polyphenylene ether contains components of 50,000 molecular weight and above in amounts of 5-20 mass% and contains components of 8,000 molecular weight and less in amounts of 12-30 mass%. The resin composition contains a hydrogenated block copolymer obtained by hydrogenating a block copolymer obtained from at least two polymer blocks A having (a) the polyphenylene ether and (b) a vinyl aromatic compound as the main constituents and at least one polymer block B having a conjugated diene compound as the main constituent, and is a hydrogenated block copolymer wherein the number average molecular weight (Mnb) of the hydrogenated block copolymer is 100,000 or less and the number average molecular weight (MnbA) of at least one of the polymer blocks A is 8,000 or more.
