Abstract

This invention relates to obtaining a propylene polymer having elastomeric properties which can be obtained directly from the polymerization reaction of propylene as a single product. The propylene polymer according to the invention comprises polymer fractions from amorphous to increasingly crystalline. The molecular weights of the polymers according to the invention, in addition to being high, extend over quite restricted ranges.
