BAPTDS can extend its chain with octamethylcyclotetrasiloxane (04) under the catalysis of acid or base or heating to obtain PSX. PSX can be used as a soft segment during use. Copolymerization reaction with other dianhydride or diamines. Polymers with high temperature and mechanical properties can be prepared. The effects of different lengths of polysiloxane (PSX) chains and changing the content of PSX in the copolymer on the mechanical properties, thermal properties, and solubility of its copolymer resin were obtained. Soap free lotion polymerization can still expand the chain of the above siloxane diamines (II), (III) and (N) by using the equilibrium reaction to generate siloxane oligomers with amino functional groups at both ends.
The silicone containing polyimides with siloxane diamine monomers (ill), (N) and CV embedded in these living parts have most excellent properties, but they have not become a research hotspot. However, most of them have complex synthesis conditions, numerous steps, and low yields. And most reactions require precious metals as catalysts, which are expensive and difficult to apply to industrial production.
