(57) [Abstract] (with correction) [PROBLEMS] To provide an acrylic copolymer which is added to a vinyl chloride resin and has excellent properties for improving processability and can be obtained as a powder having good flow properties. provide. SOLUTION: Methyl methacrylate is 60 to 95% by weight. And at least one monomer selected from alkyl methacrylate having an alkyl group having 2 to 8 carbon atoms and alkyl acrylate having an alkyl group having 1 to 8 carbon atoms In the presence of 70 to 90 parts by weight of a copolymer obtained by polymerizing a monomer mixture of 40% by weight and 0 to 10% by weight of another vinyl monomer copolymerizable with these monomers. , Methyl methacrylate, alkyl methacrylate having an alkyl group having 2 to 8 carbon atoms, alkyl acrylate having an alkyl group having 1 to 8 carbon atoms, and other vinyl monomers copolymerizable with these monomers 10 to 30 parts by weight are added and polymerized to obtain an acrylic copolymer. |
