NEUTRALISED SULFONATED ELASTOMERIC COMPOSITIONS

摘要

Neutralised sulphonated elastomeric polymers are extended by the inclusion of 5 to 200 wt. % of a non-polar process oil. Alro included are 25 to 350 wt. % of an inorganic filler and 3 to 60 wt. % of a preferential ionic plasticizer. The final composition has a viscosity of 0.73 sec<-><1> at 200 DEG C of 5 x 10<4> poises to 1 x 10<6> poises. This extended polymer can be formed into an elastomeric article.
