Solid sheared polymer blends and process for their preparation |
摘要 |
A polymer blend is produced by simultaneously blending and shearing a low ethylene content ethylene-propylene polymer and a higher ethylene content ethylene-propylene polymer to reduce their molecular weights and molecular weight distributions and to yield a product than can be recovered as a solid using conventional plastics processing equipment. The sheared blend of polymers can function as a shear stable viscosity index improver with improved low temperature properties. |
