Abstract
Provided is a method of preparing a maleimide-based copolymer, which comprises adding a monomer mixture including an aromatic vinyl-based monomer and a maleimide-based monomer to an aqueous solution consisting of an aqueous solvent and a first vinyl cyanide-based monomer and performing polymerization.
Claims8
A method of preparing a maleimide-based copolymer, comprising:
- adding a monomer mixture including an aromatic vinyl-based monomer and a maleimide-based monomer to an aqueous solution consisting of an aqueous solvent and a first vinyl cyanide-based monomer and performing polymerization,
- wherein the monomer mixture includes a second vinyl cyanide-based monomer, and
- wherein an amount of the first vinyl cyanide-based monomer is 30.0 to 90.0 parts by weight with respect to 100.0 parts by weight of the sum of the first vinyl cyanide-based monomer and the second vinyl cyanide-based monomer.
