Abstract:
A solid multimodal polymer composition comprising units derived from ethylene, alpha-olefin and diene, the polymer composition comprising:a) at least 50 weight percent based on the total polymer weight of a first fraction having a Mooney viscosity of over 120 (1+4@125Â° C.); and b) from 5 to 50 weight percent based on the total polymer weight of a second fraction having a Mooney viscosity of 120 or less (1+4@125Â° C.) and a Mn of at least 3500 g/mol, wherein the polymer composition has a tan (&dgr;) of 0.5 or less when measured at 125Â° C. and at a frequency of 10.4 rad/sec, and an overall Mooney viscosity of at least 30(1+4@125Â° C.).
