Abstract:
1. A weatherable thermoplastic resin composition comprising: (A) a (meth)acrylic acid alkyl ester-based polymer; (B) a (meth)acrylic acid alkyl ester-based oligomeric prepolymer, and (C) an aromatic vinyl-cyanide vinyl based copolymer, wherein the (meth)acrylic acid alkyl ester-based polymer (A) and the (meth)acrylic acid alkyl ester-based oligomeric prepolymer (B) form a network-shaped disperse phase, and the aromatic vinyl-cyanide vinyl based copolymer (C) forms a continuous phase, and wherein said (meth)acrylic acid alkyl ester-based oligomeric prepolymer (B) is prepared by polymerizing a mixture comprising a mercapto compound having either two or more carboxyl groups or two or more hydroxyl groups and a (meth)acrylic acid alkyl ester monomer.
