Abstract
Polymers and copolymers of propylene are modified by grafting with polyalkenylenes having a trans double bond content of higher than 30%. The preparation is carried out via thermic treatment of the propylene (co)polymer with said polyalkenylene at a temperature comprised between 200.degree. and 350.degree. C. an the presence of a free radical initiator other than peroxide.
Claims12
A process for the preparation of propylene polymers grafted with polyalkenylene, said process comprising mixing a propylene polymer with a polyalkenylene in the presence of a non-peroxide radical initiator, at a temperature of from 270.degree. to 350.degree. C., for a time period of from 0.1 to 20 minutes.
