POLYSILOXANE-HYDROCARBYLENE AMINOHYDROCARBYLENE MULTIBLOCK COPOLYMER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new amino-functional organopolysiloxane which is difficult to be colored over time, and provides a method for producing such an amino-functional organopolysiloxane in which production of cyclic by-products can be prevented, and the amino-functional organopolysiloxane can be easily synthesized without using complicated and/or troublesome operations.

SOLUTION: A polysiloxane-hydrocarbylene aminohydrocarbylene multiblock copolymer is obtained by subjecting a polysiloxane in which both terminals are capped with SiH groups and an amine or silylamine having two aliphatic unsaturated bonds in one molecule to an addition reaction.
