Curing fluorinated alkoxy phosphonitrile polymer with peroxide and aluminum compound

摘要

The curing or cross-linking of fluorinated alkoxy phosphonitrile polymers with organic peroxides is accelerated by the use of a trialkyl aluminum or a dialkyl aluminum hydride. The coating with such polymers of biomedical articles such as embolectomy catheters or Foley retention catheters made of natural or synthetic rubber is facilitated by using for the coating a solution of such polymers in an organic solvent together with an organic peroxide and the new accelerating catalyst.
