PURPOSE:To provide the titled composition excellent in the releasing effect of a molded body comprising a synthetic resin or rubber and having the excellent lasting property of said effect, obtained by containing a copolymer of specific unsaturated ester containing a polyfluoroalkyl group and specific unsaturated ester as an effective component. CONSTITUTION:Pref., 40wt% or more of unsaturated ester containing a polyfluoroalkyl group (A) represented by formula CH2=CR<1>COOR<2>Rf [wherein Rf is 1-20C polyfluoroalkyl, R<1> is H or methyl and R<2> is alkylene represented by CmH2m. Herein, (m) is 1-10] and unsaturated ester (B) represented by formula CH2= CR<3>COOR<4> (wherein R<4> is aliphatic or alyciclic hydrocarbon or alkyl) are copolymerized and the obtained copolymer is contained as an effective component to obtain the objective composition. |
