ABSTRACT:
The subject invention relates to segmented fluoropolymers of the A-B-A type where A is a crystallizable fluoropolymer segment, and B is a base-resistant elastomeric fluoropolymer segment, the segmented fluoropolymers being useful as thermoplastic fluoroelastomers which are highly resistant to attack by bases. The fluoroelastomers are useful, for example, in O-rings and shaft seals in internal combustion engines using aggressive oils and in oil well applications.
