THE SYNTHESIS OF SILICON CONTAINING POLYMERS VIA CARBANION CHEMISTRY... 

The use of highly reactive carbanions in polymer synthesis has proven to be an interesting subject. The work which has been described here indicates some of the potential for novel polymeric materials. Examination of the polymers prepared in this work hints at some of the endless possibilities for the preparation of similar materials. There are many other dicarbanions which can be used in analogous syntheses. One molecule which would be interesting to examine is the dicarbanion of 2,3-dimethyl-1,3-butadiene which would result in a silicon containing polymer that contains a backbone diene unit. Another area of interest which has emerged from this work is the preparation of polymers which contain other inorganic atoms in the polymer backbone such as tin. We believe materials such as these would have some very unique properties.

Metathesis of 1,9-decadiene and cyclooctene with trialkoxy- and trisiloxy-substituted vinylsilanes in the presence of Grubbs catalyst, carried out in appropriate conditions, leads to the formation of bis(silyl)diene with a high yield. Similar processes performed with divinyl-substituted siloxane lead to the formation of silicon-containing polymers (via ADMET copolymerization and tandem ROM/CD polymerization), thus opening a new convenient route to synthesis of unsaturated organosilicon copolymers.
