Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a soft polymer useful as a substitute for conventional soft plastic materials including polyvinyl chlorides and polyolefins. SOLUTION: The soft polymer consists of a rubber-modified polymer (C) which is obtained by polymerizing a vinyl monomer (B) containing a (meth)acrylate in the presence of a rubbery polymer (A) having a Mooney viscosity (ASTM D1646, ML(1+4)121°C) of ≤8 and which has a flexural modulus (ISO) of ≤700 MPa. Preferable rubbery polymer (A) is an ethylene-α-olefin copolymer rubber. COPYRIGHT: (C)2005,JPO&NCIPI
