There is disclosed a polymer composition which can cure rapidly to provide a release coating that has a low surface tension, said composition comprising: (A) a fluorine-containing polymer that contains at least 2 alkenyl groups in each molecule, said polymer being obtained by the copolymerization of (a) an acrylic monomer having the general formula CH2=CX-COOR' wherein X is selected from the group consisting of hydrogen and a methyl radical and R' denotes a monovalent hydrocarbon group having 4 to 15 carbon atoms which contain at least one -CF2- group, and (b) a silicone macromonomer with the general formula CH2=CX-COO-Q-(RMeSiO)n-Me2SiR'' wherein X has its previously defined meaning, Q denotes a divalent hydrocarbon group having 1 to 8 carbon atoms, R is selected from the group consisting of methyl radical and fluorine-containing monovalent hydrocarbon group having 3 to 8 carbon atoms, Me represents a methyl radical, R'' denotes a alkenyl group having 2 to 6 carbon atoms and n is an integer having a value of at least 1; (B) an organohydrogenpolysiloxane that contains at least 3 silicon-bonded hydrogen atoms in each molecule; (C) a hydrosilylation catalyst; and (D) a hydrosilylation catalyst inhibitor.
