Organopolysiloxane, method for producing the same, and curable resin composition containing the organopolysiloxane

摘要

The present invention provides organopolysiloxane comprising one or more unsaturated bond-containing group(s) in one molecule and having constitutional units F1, M1, and T in any combination of
(i) F1 and M1,(ii) F1 and T, and(iii) F1, M1, and T:;
wherein R1 represents any selected from the group consisting of a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 10 carbon atoms, a substituted or unsubstituted aryl group, and a substituted or unsubstituted aralkyl group; R2 represents an unsaturated bond-containing group having 2 to 10 carbon atoms; X represents a divalent hydrocarbon group having 2 to 10 carbon atoms; Y represents a divalent hydrocarbon group having 2 to 10 carbon atoms; and a, b, and c each independently represent an integer of 1 or larger, wherein F1 represents a unit constituting cyclic organopolysiloxane.

主权项

1. An organopolysiloxane represented by any formula selected from the group consisting of formulae (14) through (25) and (28) through (31): wherein R1 represents any selected from the group consisting of a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 10 carbon atoms, a substituted or unsubstituted aryl group, and a substituted or unsubstituted aralkyl group, in which the substituted R1 is substituted with a hydroxy containing group, a cyano group, and/or a halogen containing group; R2 represents an unsaturated bond-containing group having 2 to 10 carbon atoms; Y represents a divalent hydrocarbon group having 2 to 10 carbon atoms; m represents an integer of 0 to 2000; n represents an integer of 0 to 20; and r represents an integer of 0 to 20.
