Description

[0001] Specification of an industrial invention in the name of SOLVAY SOLEXISS.p.A. of Italian nationality, headquartered in Milano, via Turati 12. technical field

[0002] The present invention relates to perfluoroelastomers having a Tg (glass transition temperature) below -10°C and an improved combination of mechanical and compression set properties over a wide temperature range, at high and low temperatures.

[0003] More specifically, the present invention relates to perfluoroelastomers having a Tg below -10°C and having substantially no -COF end groups which are not detectable by the method described below. The perfluoroelastomers of the present invention show improved molecular weight as shown by improved intrinsic viscosity and are obtainable by a polymerization process with improved productivity. Background technique

[0004] Perfluoroelastomers are known to be particularly useful polymers in the aerospace, petroleum, petrochemical and semiconductor industries due to...
