Title:
ポリフェニレンスルフィド樹脂組成物、その製造方法および成形体
Document Type and Number:
Japanese Patent JP7081500
Kind Code:
B2
Abstract:
The present invention provides a polyphenylene sulfide resin composition including: from 99.5 to 51 parts by weight of a polyphenylene sulfide resin (A); from 0.5 to 49 parts by weight of an aromatic vinyl compound block copolymer (B) containing at least one functional group selected from the group consisting of a carboxyl group, an acid anhydride group, a hydroxyl group, an amino group, an epoxy group and an isocyanate group; and from 0.1 to 2.0 parts by weight, with respect to 100 parts by weight of the total amount of the polyphenylene sulfide resin (A) and the aromatic vinyl compound block copolymer (B), of an alkoxysilane compound (C) containing at least one functional group selected from the group consisting of an epoxy group, an amino group and an isocyanate group; wherein the morphology (phase structure) of the polyphenylene sulfide resin composition has a sea-island structure in which the polyphenylene sulfide resin (A) forms a continuous phase (sea phase), and the aromatic vinyl compound block copolymer (B) forms a dispersed phase (island phase) dispersed in a number average dispersed particle size of 1,000 nm or less. The present invention provides a polyphenylene sulfide resin composition having an excellent impact resistance strength and water pressure resistance strength.
