NOVEL METHOD FOR THE PREPARATION OF VINYL CARBONATE CAPPED POLYDIMETHYLSILOXANES

摘要

This invention relates to the preparation of vinyl carbonate capped polydimethylsiloxanes. More specifically, the invention relates to the preparation of vinyl carbonate capped polydimethylsiloxanes for use in forming optically clear medical devices by the ring opening siloxane rearrangement polymerization using water content standardized cation exchange resins as the catalytic species.
