Curable silicone composition

摘要

A curable silicone composition having high compatibility with organic polymers, which comprises (a) 100 parts by weight of a hydroxyl group-containing organopolysiloxane represented by the following formula (I) and (b) 1-50 parts by weight of an isocyanate compound having at least two isocyanate groups per molecule, wherein the number of the hydroxyl groups per molecule in the component (a) plus the number of the isocyanate groups per molecule in the component (b) is at least 5: wherein R1 is a monovalent saturated hydrocarbon group; R2 is a phenyl-substituted alkyl group represented by C6H5-(CH2)p-CH(R4)-CH2-; R3 is a hydroxyl-substituted alkyl group represented by -CH2-CH2-CH2-O-(C2H4O)q-H; two R groups are the same group or different groups selected from the groups represented by R1, R2 or R3; R4 is a hydrogen atom or the same group as R1; l is 0 or a positive number, m is a positive number and n is a positive number of no less than 2, provided that 0.10
