FREE FILMS MADE OF CURED ORGANOPOLYSILOXANE RESINS, PROCESS FOR PRODUCTION THEREOF, AND LAMINATED FILMS

摘要

A free-standing film comprising a cured organopolysiloxane resin obtained by conducting a cross-linking reaction between (A) an organopolysiloxane resin represented by the following average siloxane unit formula: [R 1 a R 2 3-a SiO 1/2 ] v [R 3 SiO 3/2 ] w (1) or [R 1 a R 2 3-a SiO 1/2 ] x [R 3 SiO 3/2 ] y [SiO 4/2 ] z (2) (where R 1 designates univalent hydrocarbon groups of one or more than one type selected from alkyl groups having 1 to 4 carbon atoms and univalent aromatic hydrocarbon groups having 6 to 8 carbon atoms; R 2 designate alkenyl groups having 2 to 6 carbon atoms; R 3 designates alkyl groups with 1 to 4 carbon atoms or univalent aromatic hydrocarbon groups having 6 to 8 carbon atoms; at least 50 mole % of R 3 groups being phenyl groups; "a" is 0, 1, or 2; 0.8‰¦w<1.0 and v+w=1;0
