ABSTRACT:
The present invention relates to resin compositions having a good compatibility of polyphenylene ether and polyamide and a natural color, which comprise (A) 5 to 95 parts by weight of a polyphenylene ether, (B) 1 to 50 parts by weight of a functionalized aromatic vinyl graft copolymer which is prepared by melt blending 100 parts by weight of a copolymer which is prepared by graft polymerizing 20 to 99 parts by weight of aromatic vinyl monomers onto 1 to 80 parts by weight of synthetic rubber polymer, 0.01 to 2 parts by weight of an organic peroxide and 0.01 to 10 parts by weight of reactive monomers having an unsaturated carboxylic acid or anhydride group, and (C) 5 to 95 parts by weight of a polyamide and optionally (D) up to 40 parts by weight of a synthetic resinous impact modifier.
