PURPOSE: To obtain a molded article having excellent surface characteristics, and imparted with water and oil repellency, releasability, low frictional property, stain-proofing property, etc., by adding a polymerizable compound containing a perfluoroalkyl group and a radical polymerization initiator to an acrylic resin, and molding the composition under melting.

CONSTITUTION: An acrylic resin is mixed with a polymerizable compound containing a perfluoroalkyl grup and a radical polymerization initiator, and molded under melting. The polymerizable compound is preferably the compound of formula I or II (Rf is 3W20C fluoroalkyl or perfluoroalkyl; R1 is 1W5C alkyl; R2 and R4 are 1W20C alkylene; R3 and R5 are H or methyl). The radical polymerization initiator is an organic peroxide or an azo compound. The amount of the polymerizable compound is 0.1W5pts.wt., preferably 0.25W1pt.wt. per 100pts. wt. of the acrylic resin.
