Problems solved by technology

However, if a molded body is produced according to known techniques, in order to facilitate the segregation of fluorine compounds on the surface, it is necessary to use a fluorine compound with poor compatibility with thermoplastic resins, so it must be carried out under specific conditions.
Moreover, even if kneading can be performed under normal conditions, there is a problem that the amount of fluorine compound added needs to be increased, which is not ideal in terms of cost and process.

Abstract

The invention relates to a resin composition and molded product thereof. The molded product is obtained by the resin composition. The resin composition which comprises (A) a thermoplastic resin and (B) a fluoropolymer comprising structural units derived from an acrylate ester represented by the general formula (I): [wherein X is hydrogen, methyl, fluoro, chloro, bromo, iodo, CFX1X2 (wherein X1 and X2 are each hydrogen, fluoro, chloro, bromo, or iodo), cyano, straight-chain or branched fluoroalkyl having 1 to 21 carbon atoms, substituted or unsubstituted benzyl, or substituted or unsubstituted phenyl; Y is an aliphatic group having 1 to 10 carbon atoms or the like; and Rf is a straight-chain or branched fluoroalkyl or fluoroalkenyl group having 1 to 6 carbon atoms]. The composition can give moldings excellent in water repellency and oil repellency.

Description

Technical field [0001] The present invention relates to a resin composition and its molded body. The molded body of the present invention is characterized in that the fluoropolymer is concentrated on the surface of the molded body. The molded body can be used as household products, stationery, interior materials, sanitary products, medical products, and the like. Background technique [0002] In order to impart water and oil repellency to the surface of a molded body, a technique of applying fluorine treatment to the surface is known in the past. However, in the method of performing fluorine treatment after molding, the durability of the water and oil repellent function is weak, and there is a problem that the water and oil repellency decreases due to repeated use. In order to solve this problem, studies have been made to add a fluorine compound to the resin before the molding process and perform melt kneading to segregate the fluorine component on the surface after molding, ther...
