Process for preparing propylene copolymers

摘要

There is provided a process for the copolymerisation of propylene with at least one C_4-20 alpha-olefin or C_4-20 diene in a reaction medium in the presence of a catalyst system at a temperature of greater that 80° C. or at a temperature and pressure above the critical temperature and pressure of the reaction medium. Under such conditions, comonmer incorporation is higher than under standard conditions.
