Japanese Patent JP2869304

Kind Code:

B2

Abstract:

Novel organopolysiloxanes having one silanol group within a molecule and the method for manufacturing them at high purity and high yield. The organopolysiloxanes having a silanol group are expressed by the formula (1) below: wherein R<1> s a monovalent organic group with 1 to 8 carbon atoms, each of R<2>, R<3> and R<4> is a monovalent organic group with 1 to 8 carbon atoms or a siloxyl group expressed by -OSiR<5>R<6>R<7> wherein R<5>, R<6>, and R<7> are independently substituted or unsubstituted monovalent hydrocarbon groups with 1 to 8 carbon atoms, Y is a hydrogen atom, a halogen atom, or a monovalent organic group of 1 to 12 carbon atoms, n is an integer of from 0 to 12, and a is either 0 or 1, with the proviso that the grouping Y-(CH2)n-Si is not H-Si, CH3-Si or a hydrolyzable silyl group.
