    摘要： Catalyst Systems, processes of forming the same and polymers and polymerization processes are described herein. The process of forming the catalyst system generally includes providing a first compound including a magnesium dialkoxide and aluminum alkoxide: contacting the first compound with a first agent and a second agent to form a solution of reaction product “A”, the first agent including a titanating agent and the second agent including a first metal halide; contacting the solution of reaction product “A” with a third agent to form a solid reaction product “B”, the third agent including a second metal halide: contacting the solid reaction product “B” with a fourth agent to form a solid reaction product “C”, the fourth agent including a third metal halide: optionally contacting the solid reaction product “C” with a fifth agent to form a solid reaction product “D”, the fifth agent including a fourth metal halide; and contacting the solid reaction product “C” or “D” with a sixth agent to form a catalyst component, the sixth agent including a first organoaluminum compound.

    摘要： Films and processes of forming the same are described herein. The processes generally include providing a propylene-based polymer; contacting the propylene-based polymer with polylactic acid in the presence of a modifier to form a polymeric blend, wherein the modifier is selected from epoxy-functionalized polyolefins, maleic anhydride modified polyolefins, ethylene-methacrylate copolymers, styrene-ethylene-butadiene-styrene (SIBS) polymers, and combinations thereof; forming the polymeric blend into a film; and monoaxially orienting the film.
