Abstract:
A polyorganosiloxane compound which contains in the molecule a silicone oil structure and a silicone resin structure having at least one alkoxyl group and is compatible with a silicone resin, said polyorganosiloxane being obtained by allowing the following polyorganosiloxane (a1):(a1) a polyorganosiloxane represented by the average compositional formula (1): R1aR2bSi(OR3)cO(4âˆ’aâˆ’bâˆ’c)/2â€ƒâ€ƒ(1) wherein R1 is at least one member selected from the group consisting of a substituted or unsubstituted alkyl group and a substituted or unsubstituted aryl group; R2 is a group containing an aliphatic unsaturated double bond; R3 is an alkyl group having 1 to 4 carbon atoms which may have an ether linkage; and a, b and c are numbers that satisfy the following relation: 0&lE;a<1.5, 0.01&lE;b&lE;1, 0.5&lE;a+b&lE;1.8, 0.01&lE;c&lE;2.5 and 1&lE;a+b+c&lE;3; and having at least one aliphatic unsaturated double bond in the molecule, to react with the following polyorganosiloxane (a2): (a2) a polyorganosiloxane represented by the general formula (2): wherein R1 is as defined in the above formula (1), and n is a number of from 0 to 1,000, in the presence of a hydrosilylation catalyst.
