Abstract
This invention relates to a polysiloxane with a comb-like structure and with tertiary amine groups, and the method of preparing the same. The polysiloxane of the invention does not include any active hydrogen groups so that the amount of the amine groups can increase, which in turn improves the effect of self-emulsification. This makes the polysiloxane applicable in water-soluble resins, for example as an accelerator in water-soluble epoxy resin or water soluble fiber dying treating agent. When used as fiber treatment agent, the polysiloxane will not cause yellowing.
