New organopolysiloxane, obtained by addition of silicon hydride group containing organopolysiloxane compounds at vinylsiloxane compounds, useful in hardenable, abhesive coating mass, which is useful for coating a molded body

摘要

Organopolysiloxane compounds (A), obtained by addition of silicon hydride (SiH)-group containing organopolysiloxane compounds (I) at vinylsiloxane compounds (II) in the presence of platinum or rhodium catalyst, are new. Organopolysiloxane compounds (A), obtained by addition of silicon hydride (SiH)-group containing organopolysiloxane compounds of formula (I) at vinylsiloxane compounds (II) of formula CH2=CH-Si(R1)2-O-[Si(R1)2-O]d-Si(R1)2-CH=CH2 in the presence of platinum or rhodium catalyst, provided that (I) is added in at least 6-fold, preferably 8 fold, molar excess related to (II), subsequently partially or completely reacting the SiH group, in the presence of catalysts, with at lease one alcohol, (meth)acrylated monoalcohol or polyalcohol, optionally in combination with at least another alcohol, preferably optionally saturated, aromatic, aliphatic-aromatic mono and polyalcohol, optionally halo atom, preferably fluoro atom, containing mono- or polyalcohol, polyether monoalcohol, polyether polyalcohol, polyester monoalcohol, polyesterpolyalcohol or aminoalcohol, preferably N-alkyl-, arylamino-EO- (where EO is -(C2H4O)nH; n is greater than or equal to 1), -PO oxide-alcohol (where PO is -(C3H6O)mH; m is greater than or equal to 1), N-alkyl or arylamino alcohol, are new. R1 : 1-20C aliphatic or aromatic hydrocarbon; R2 : R1 or H (provided that at least 3 R2 is H); a : 5-500; b : 1-50; c : 0-50 (preferably 0); and d : 60-1000. An independent claim is also included for hardenable, abhesive coating mass comprising (A). [Image].
