Title:
BROMOSULPHONATED FLUORINATED CROSSLINKABLE ELASTOMERS BASED ON VINYLIDENE FLUORIDE HAVING VERY LOW Tg AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO2001096268
Kind Code:
A3
Abstract:
The invention concerns compounds of formula (I) F2C=CFX(CY2)nBr wherein: X represents an oxygen atom or no atom at all; Y represents a hydrogen or fluorine atom; and n is a natural integer ranging between 0 and 10 inclusive; and their use in the synthesis of fluorinated copolymers then in the synthesis of bromosulphonated fluorinated elastomers, having a low glass transition temperature.
