Polycarbosilane Elastomers via Chain-Internal and Chain-End Latent Crosslinking

Abstract

The mission/objective of this work has been to identify a new class of hybrid polymers based on carbosilane/carbosiloxane chemistry, the objective being to create elastomers having excellent solvent resistance, high initial modulus, elasticity greater than 600%, and tensile strengths 2X greater than existing elastomers. Polymers have been synthesized and are being examined for their performance. All the required parameters for performance have been met excepting the tensile strength goal of 2X existing elastomers. While the project is now concluded from a funding perspective, we continue to examine the concept of dual latent crosslinking to achieve the tensile strength goal.
