✦ Synopsis


A new method for the preparation of functionalized polyolefins is presented. The method consists of two steps: (i) copolymerization of ethylene and/or an cy-olefin with 1-iodo-3-butene (ii) elimination or substitution reaction of the iodine atom, by reaction with an organic salt of potassium, in the presence of a crown ether.

The synthesis of ethylene/propylene/ I-iodo-3-butene copolymers with Vanadium based catalysts as well as the dehydrohalogenation reaction on the copolymers are discussed.

The first example of ethylene/propylene/ 1,3-butadiene copolymers, where the diene has exclusively 1,2 configuration, is presented.
