Abstract: PURPOSE: An aromatic vinyl-based copolymer is provided to productivity, heat durability and economic advantages. CONSTITUTION: An aromatic vinyl-based copolymer comprises 10-40 weight% of an acrylonitrile-based monomer, 30-70 weight% of a substituted aromatic vinyl-based monomer, and 5-30 weight% of unsubstituted aromatic vinyl-based monomer, 0.01-14 weight% of a (meth)acrylate-based monomer. The glass transition temperature(Tg) of the aromatic vinyl-based copolymer is 110-120 °C and the number average molecular weight is 30,000-70,000 g/mol. The composition comprises the aromatic vinyl-based copolymer and one or more resin selected from a styrene-based graft copolymer resin and a styrene-based copolymer resin.

Abstract: PURPOSE: An acryl-based elastomers copolymer for substituting for polyvinyl chloride and an environmentally-friendly composition including thereof are provided to maintain similar physical property as polyvinyl chloride and substitute for polyvinyl chloride. CONSTITUTION: A manufacturing method of An acryl-based elastomers copolymer for substituting for polyvinyl chloride comprises the following steps: forming a core by polymerizing more than one kind of monomers which is selected from acrylate ester, meta acrylic acid ester, methacrylic acid hydroxyalkyl ester; forming a first shell by polymerizing after adding more than one kind of monomers which is selected from ester acrylate, meta acrylic acid ester, methacrylic acid hydroxyalkyl ester, acrylic acid hydroxyalkyl ester to the core; and forming a second shell by performing polymerization after adding acid and acryl-based monomer to the first shell.
