Abstract

The invention relates to the polymerization of olefins by using a catalyst consisting of an Al-trialkyl compound and a spherical catalyst component comprising a titanium compound and optionally an electron-donor compound supported on anhydrous magnesium chloride, characterized by a surface area between 20 and 250 m2/g, porosity between 0.25 and 0.5 cm3/g, and an X-ray spectrum where the magnesium chloride reflections are present at 2 v- values of 35 degree and 14.95 degree, or where the reflection at 35 degree is substituted by a reflection with the maximum intensity between 33.5 degree and 35 degree and the reflection of 2 v-value at 14.95 degree is absent. The invention further relates to a polymer and copolymer thus produced.
