摘要: Processes for producing impact copolymers are provided. Ethylene and at least one comonomer can be polymerized in the presence of or more catalysts, polypropylene particles, an inert solvent to produce copolymer. The particles have a weight average particle size along longest cross-sectional length thereof about 0.05 mm 5 pore volume less than 80%. present amount 0.1 2 times particles.
