FIELD: chemistry.
SUBSTANCE: perfluoro-elastomers have Tg below -10°C and amount of terminal -COF groups less than 0.05 mmol/kg. Perfluoro-elastomers contain: (A) from 1% to 100% monomer of formula CF2=CFOCF2OCF3 and (B) from 0% to 100% one or more perfluorinated comonomers with at least one ethylene unsaturation. Comonomer (B) is TFE, or a mixture of comonomers (B) contains TFE.
EFFECT: improved mechanical properties and compression set.
