METHOD OF PREPARING GRAFT POLYMER

Provided is a method of preparing a graft polymer, which includes: adding a diene-based rubber polymer, a first monomer mixture including a (meth)acrylate-based monomer and an aromatic vinyl-based monomer, and a reactive ultraviolet (UV) stabilizer to a reactor and carrying out polymerization to pre...

Beschreibung
Zusammenfassung:	Provided is a method of preparing a graft polymer, which includes: adding a diene-based rubber polymer, a first monomer mixture including a (meth)acrylate-based monomer and an aromatic vinyl-based monomer, and a reactive ultraviolet (UV) stabilizer to a reactor and carrying out polymerization to prepare a composite rubber polymer; and graft-polymerizing a second monomer mixture including a (meth)acrylate-based monomer, an aromatic vinyl-based monomer, and a vinyl cyanide-based monomer to the composite rubber polymer to prepare a graft polymer, wherein the reactive UV stabilizer is added in an amount of 0.1 to 2 parts by weight based on 100 parts by weight of the sum of the diene-based rubber polymer, the first monomer mixture, and the second monomer mixture.
