✦ 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.

Chlorinated organic polymers were prepared, characterized and used as supports for TiC14. The activity of the new catalysts in the polymerization of ethylene was compared with that observed for TiCl, supported on non-chlorinated polymers. It was found that the new catalysts have initial activities o
