Acrylic processing aid, method for preparing the same and polyvinylchloride resin composition comprising the same
First Claim
1. A method for preparing an acrylic processing aid having a core-shell structure comprising:
- polymerizing a methyl methacrylate monomer and an alkyl acrylate monomer having 1 to 18 carbon atoms to prepare a polymer for the core; and
polymerizing the core, a methyl methacrylate monomer and an alkyl acrylate monomer having 1 to 18 carbon atoms to prepare the core-shell structure,wherein the polymer for the core has a weight-average molecular weight ranging from 10,000,000 to 18,000,000 g/mol.
