Abstract
Disclosed are plastic copolymers of propylene with linear dienes having conjugated double bonds, in particular with butadiene, characterized by a molar ratio between the dienic units in configuration 1,2 and those in configuration 1,4 higher than 0.2, preferably higher than 1. Such copolymers are prepared by copolymerization of propylene with linear dienes in the presence of stereospecific catalysts comprising a halogen Ti compound supported on a Mg halide. The copolymers can be reacted with radically polymerizable monomers, thus obtaining functionalized products suited to be transformed into films having good adhesion characteristics.
