Abstract (en)

[origin: WO9962916A1] Compositions of unstrained perfluorinated organo substituted cyclosiloxanes of formula (I) wherein m is an integer of 1 to 12; n is an integer of 1 to 4; X is a divalent radical which may include O, NH, N(CH3), OC(O), NHC(O), N(CH3)C(O)CH2; and R<F> is a perfluorinated straight chain or branched chain monovalent alkyl radical of 1 to 25 carbon atoms; or R<F> is a perfluorinated ether radical of general formula (II) wherein p is an integer of 1 to 10 are described, along with copolymer compositions prepared from these cyclopolysiloxanes and from mixtures of these cyclosiloxanes and other siloxanes.
