The present invention provides a novel amino-functional organopolysiloxane which is difficult to be colored over time or by heating, and provides a method for producing a novel amino-functional organopolysiloxane which is difficult to be colored over time or by heating, in which production of cyclic by-products can be prevented, and the aforementioned amino-functional organopolysiloxane can be easily synthesized without using complicated and/or troublesome operations. 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.

The present invention relates to a process for producing an aramid silicone polymer. The present invention is characterized by reacting (A) a both-terminal amino-modified diorganopolysiloxane having a group represented by the following formula: —B—NH2 wherein B represents a divalent hydrocarbon group, at both terminals of a molecular chain, (B) an aromatic diamine, and (C) an aromatic dicarboxylic acid dihalide, in the presence of (D) an inorganic base, in (S1) water and (S2) an aprotic organic solvent, at a temperature of 10° C. or more. The present invention does not have to be carried out at a low temperature, and by-products can be easily treated. Furthermore, the present invention does not require a large amount of a reprecipitation solvent, and therefore it can be suitably used in mass production of an aramid silicone polymer.
