Abstract

Abstract @ A polyphenylene ether resin composition comprising (A) a polyphenylene ether resin, and (B) an aromatic polyamide having a melting point of up to 330°C composed mainly of at least one kind of recurring structural units containing an aromatic nucleus represented for formula (I) wherein R' represents an alkylenephenylene or dialkylenephenylene group, or formula (II) wherein R 2 represents a phenylene, dialkylenephenylene or biphenylene group or a group of the following formula in which X represents an alkylene group having 1 to 5 carbon atoms, an oxygen atom, a sulfur atom, a carbonyl group or a sulfonyl group, and R 3 represents an alkylene group having 3 to 10 carbon atoms, a phenylene group or a naphthylene group.

A polyphenylene ether resin composition comprising (A) a polyphenylene ether resin, and (B) an aromatic polyamide having a melting point of up to 330°C composed mainly of at least one kind of recurring structural units containing an aromatic nucleus represented by formula (I) wherein R 1 represents an alkylenephenylene or dialkylenephenylene group, or formula (II) wherein R represents a phenylene, dialkylenephenylene or biphenylene group or a group of the following formula in which X represents an alkylene group having 1 to 5 carbon atoms, an oxygen atom, a sulfur atom, a carbonyl group or a sulfonyl group, and R 3 represents an alkylene group having 3 to 10 carbon atoms, a phenylene group or a naphthylene group.
Claim 2
Dependent Claim 117 words
A polyphenylene ether resin composition comprising (A) a polyphenylene ether resin, and (B) an aromatic polyamide having a melting point of up to 330°C composed mainly of at least one kind of recurring structural units containing an aromatic nucleus represented by formula (I) wherein R 1 represents an alkylenephenylene or dialkylenephenylene group, or formula (II) wherein R represents a phenylene, dialkylenephenylene or biphenylene group or a group of the following formula in which X represents an alkylene group having 1 to 5 carbon atoms, an oxygen atom, a sulfur atom, a carbonyl group or a sulfonyl group, and R 3 represents an alkylene group having 3 to 10 carbon atoms, a phenylene group or a naphthylene group.
Claim 3
Dependent Claim 43 words
A resin composition according to claim 1 wherein the polyphenylene ether resin is a homopolymer of phenylene ether, a copolymer of phenylene ether, a grafted phenylene ether polymer, or a blend of any one of these polymers with another resin or an elastomer.
Claim 4
Dependent Claim 17 words
A resin composition according to claim 1 or 2 wherein the other resin is a polystyrene-type resin.
