Abstract:

Fluoroalkyleneether silicate copolymers are synthesized by the polycondensation of a bis-dimethylcarbinol containing a fluoroalkyleneether segment and bisdimethylamino methylvinylsilane. The copolymers are useful in applications, e.g., as seals and sealants, involving use temperatures ranging from about -90 C to 600 deg. C. They are particularly useful when blended with a fluorocarbon elastomer, enhancing the strength and low temperature flexibility of the elastomer. Author
