Abstract
Abstract Organopolysiloxanes having two different functional groups selected from the group consisting of 3-glycidoxy-propyl, 2-(3′,4′-epoxycyclohexyl)ethyl, 3-hydroxypropyl, 3-(2′-hydroxyethoxy)propyl, 3-acryloxypropyl, and 3-methacryloxypropyl groups are more compatible with organic resins and more effective for tailoring the organic resins. They are produced by hydrosilylation of organohydrogenpolysiloxanes with functional group-containing alkenes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
73 words
An organopolysiloxane of the following average composition formula (1): wherein X and Y are different organic groups selected from the group consisting of 3-glycidoxypropyl, 2-(3′,4′-epoxy-cyclohexyl)ethyl, 3-hydroxypropyl, 3-(2-hydroxyethoxy)propyl, 3-acryloxypropyl, and 3-methacryloxypropyl groups, R is an alkyl group having 1 to 6 carbon atoms or phenyl group, and letters a, b and c are positive numbers within the range: 1 ≦ a ≦ 20, 1 ≦ b ≦ 10, and 1 ≦ c ≦ 10.
Claim 2
Dependent Claim
67 words
An organopolysiloxane of the following average composition formula (2): wherein X and Y are different organic groups selected from the group consisting of 3-glycidoxypropyl, 2-(3′,4′-epoxy-cyclohexyl)ethyl, 3-hydroxypropyl, 3-(2′-hydroxyethoxy)propyl, 3-acryloxypropyl, and 3-methacryloxypropyl groups, R is an alkyl group having 1 to 6 carbon atoms or phenyl group, and letters a and b are positive numbers within the range: 1 ≦ a ≦ 20 and 1 ≦ b ≦ 10.
Claim 3
Dependent Claim
93 words
A method for producing an organopolysiloxane as set forth in claim 1, comprising the steps of: adding b mol of an unsaturated compound selected from the group consisting of allyl glycidyl ether, 1-vinyl-3,4-epoxycyclohexane, allyl alcohol, allyl glycol, allyl acrylate, and allyl methacrylate to SiH of an organohydrogenpolysiloxane of the following average composition formula (3): wherein R, a, b, and c are as defined in claim 1, and adding c mol of another unsaturated compound selected from the same group as above to c mol of unreacted SiH of the organohydrogenpolysiloxane of formula (3).
Claim 4
Dependent Claim
79 words
A method for producing an organopolysiloxane as set forth in claim 2, comprising the step of: adding an unsaturated compound selected from the group consisting of allyl glycidyl ether, 1-vinyl-3,4-epoxy-cyclohexane, allyl alcohol, allyl glycol, allyl acrylate, and allyl methacrylate to SiH of an organohydrogenpolysiloxane of the following average composition formula (4): wherein Y, R, a, and b are as defined in claim 2, said unsaturated compound forming a functional group different from Y of the organohydrogenpolysiloxane of formula (4).
Claim 5
Dependent Claim
80 words
A method for producing an organopolysiloxane as set forth in claim 1, comprising the step of: adding an unsaturated compound selected from the group consisting of allyl glycidyl ether, 1-vinyl-3,4-epoxy-cyclohexane, allyl alcohol, allyl glycol, allyl acrylate, and allyl methacrylate to SiH of an organohydrogenpolysiloxane of the following average composition formula (3′): wherein X, R, a, b, and c are as defined in claim 1, said unsaturated compound forming a functional group different from X of the organohydrogenpolysiloxane of formula (3′).
