摘　　要：在复合型外给电子体的作用下,催化丙烯单体聚合,获得一种高模量、刚韧平衡的聚丙烯基础树脂。经测定,该聚丙烯熔体指数在20±2g/min(2.16kg),常温冲击强度不低于8KJ/M^2、模量不低于1800MPa。Under the action of composite external electron donor, the polymerization of propylene monomer was catalyzed to obtain a polypropylene base resin with high modulus and balance of rigidity and toughness. The melt index of the polypropylene was determined to be 20 2 g/min（ 2. 16 kg）, the impact strength at room temperature was not less than 8 kj/m^2, and the modulus was not less than 1800 MPa.
