Abstract:
PCT No. PCT/KR93/00081 Sec. 371 Date Apr. 21, 1994 Sec. 102(e) Date Apr. 21, 1994 PCT Filed Sep. 7, 1993 PCT Pub. No. WO94/05715 PCT Pub. Date Mar. 17, 1994Polymeric glass modifier having a partially crosslinked structure capable of effectively reducing the surface gloss of a thermoplastic resin, is prepared by (a) emulsion polymerizing an acrylic monomer, an ethylenically unsaturated cyanide compound end, optionally, an aromatic vinyl monomer to obtain a copolymer latex of a linear structure; (b) conducting a crosslinking emulsion polymerization of the resultant linear copolymer latex obtained in step (a) with an addition of the same monomers used in step (a), an acrylamide inter-particle crosslinking agent and an ethylenically unsaturated crosslinking agent to produce a partially crosslinked latex; and (c) coagulating and interparticle crosslinking the partially crosslinked latex obtained in step (b) with an addition of an acid to obtain the polymeric gloss modifier.
