ABSTRACT:
A continuous process for preparation of propylene-ethylene block copolymer suitable for moldings with high rigidity and high impact resistance are provided, which process is a continuous process for preparation of highly rigid propylene-ethylene block copolymers, wherein propylene and ethylene are polymerized in the specified 2 steps with use of a catalyst system comprising (A) a solid catalyst component containing Ti, Mg, halogen and polyvalent carboxylic ester, (B) an organic aluminium compound, as well as (C) an organic silicon compound expressed by the general formula R.sup.4.sub.x R.sup.5.sub.y Si(OR.sup.6).sub.z (wherein, x+y+z=4), and wherein the ratio between the maximum value and the minimum value of MFR(l)) is
