Chain Propagation/Step Propagation Polymerization Chemistry. The Preparation of Solvent Resistant Well Phase-Separated Thermoplastic Elastomers
Abstract
The essence of the research consists of synthesizing unsaturated, chlorofunctionalized carbosilanes or carbosiloxanes as a backbone polymer, and recent work with model compounds suggests that these syntheses will be successful. These chlorofunctionalized backbone polymers will be converted into either solvent resistant elastomers or high Tg materials via nucleophilic grafting reactions, chemistry which is reminiscent of the work done with polyphosphazene backbones. Thus, the goals of this research are: to synthesize a variety of unsaturated polycarbosilanes and carbosiloxanes functionalized with the silicon-chlorine bond, to graft low and high molecular weight sidechains on these backbones to tailor their physical behavior to specific needs, and, to demonstrate that these polymers can be recycled via depolymerization. As is normally the case, full structural characterization work will accompany all phases of this research. A successful effort will lead to the creation of recyclable materials for a variety of applications including lubricants, face masks, high performance engineering plastics, coatings, and self lubrication plastics. The final report summarized the research results. Polymerization chemistry, Elastomers, Thermoplastic Elastomers, Polycarbosilanes, Carbosilanes, Polymers.
