Fluorosilicone polydimethylsiloxane equilibration chainstopper and process for manufacture

摘要

A fluorosilicone polydimethylsiloxane equilibration chainstopper and process for making same are disclosed. The chainstopper has a fluorosilicone content in the range of 30 mole percent to 60 mole percent and is a preferred chainstopper in equilibration reactions in the production of vinyl-stopped fluorosilicone polydimethylsiloxane copolymers.
