Process for producing silane-modified polyphenylene ether and thermoplastic resin composition containing the same

TL;DR: A process for terminal modified polyphenylene ether represented by formula (III): as mentioned in this paper, where Q 1 represents a halogen atom, a primary of secondary alkyl group, a phenyl group, an aminoalkyl group and a hydrocarbon oxy group, or a halo-hydrocarbon oxy groups; n represents an integer of at least 10; X represents an oxygen atom or a nitrogen atom.

Abstract: A process for producing a terminal-modified polyphenylene ether represented by formula (III): ##STR1## wherein Q 1 represents a halogen atom, a primary of secondary alkyl group, a phenyl group, an aminoalkyl group, a hydrocarbon oxy group, or a halo-hydrocarbon oxy group; Q 2 represents a hydrogen atom, a halogen atom, a primary or secondary alkyl group, a phenyl group, a haloalkyl group, a hydrocarbon oxy group, or a halo-hydrocarbon oxy group; n represents an integer of at least 10; X represents an oxygen atom or a nitrogen atom; R 1 represents an alkylene group having from 1 to 12 carbon atoms; R 2 and R 3 each represents a hydrocarbon group having from 1 to 6 carbon atoms; s represents 1 when X is an oxygen atom, or 2 when X is a nitrogen atom; and t represents an integer of from from 1 to 3, which comprises reacting a polyphenylene ether represented by formula (I): ##STR2## wherein Q 1 , Q 2 , and n are as defined above, with a compound represented by formula (II): ##STR3## wherein X, R 1 , R 2 , R 3 , s, and t are as defined above; a process for producing an alkoxysilylated polyphenylene ether represented by formula (V): ##STR4## wherein Q 1 , Q 2 , and n are as defined above; R 11 represents a bond or an alkylene group having from 1 to 12 carbon atoms; R 12 and R 13 each represents a hydrocarbon group having from 1 to 6 carbon atoms; and m represents an integer of from 1 to 3, which comprises reacting a polyphenylene ether represented by formula (I) shown above with a compound represented by formula (IV): ##STR5## wherein R 11 , R 12 , R 13 , and m are as defined above; and Y represents a halogen atom; and a thermoplastic resin composition comprising the modified polyphenylene ether of formula (III) or (IV) with a saturated polyester, a polyamide, or a modified olefin resin.
