PERFLUOROELASTOMER CURING

Nitrile containing perfluoroelastomers are cured by a combination of a peroxide, a coagent, and a catalyst which causes crosslinks to form using the nitrile groups. The method is relatively fast and economical, and gives vulcanizates which have excellent high temperature properties. Triphenyltin hyd...

Zusammenfassung:	Nitrile containing perfluoroelastomers are cured by a combination of a peroxide, a coagent, and a catalyst which causes crosslinks to form using the nitrile groups. The method is relatively fast and economical, and gives vulcanizates which have excellent high temperature properties. Triphenyltin hydroxide is an exceptionally good catalyst for the formation of crosslinks from nitrile groups in perfluoroelastomers.
