Process for preparing vinyl chloride resin-acrylic graft copolymer composition |
| abstract |
A vinyl chloride resin composition is prepared by (1) preparing an acrylic elastomer (A) by (a) polymerizing 30 to 50% by wt of an aromatic vinyl monomer in the presence of a polyfunctional cross-linking agent having at least one allyl group and a carboxylate anion surfactant as an emulsifier at a pH maintained between 7.0-9.5 and then (b) graft-polymerizing 50 to 70% by wt of an alkyl acrylate of 2 to 10 carbon atoms in the alkyl group onto said polymerized aromatic vinyl polymer in the presence of from 0.1 to 3 parts by wt of a polyfunctional cross-linking agent with at least one allyl group based on the weight of the sum of said aromatic vinyl monomer and said alkyl acrylate; (2) preparing a graft copolymer (B) by graft-polymerizing from 20 to 70 parts by wt of an aromatic vinyl monomer and methyl methacrylate onto 30 to 80 parts by weight of said acrylic elastomer (A) wherein from 70% to 20% by wt of said aromatic vinyl monomer is first graft-polymerized onto said elastomer (A) in the presence of an oil soluble initiator and then graft-polymerizing from 30 to 80% by wt of methyl methacrylate onto said grafted elastomer; and (3) mixing from 60 to 97 parts by wt of a vinyl chloride polymer with 3 to 40 parts by wt of said graft copolymer (B). |
