Synthesis and Application of New Carboxyl Modified Silicone Oil

A kind of new carboxyl and vinyl co-modified silicone oil (Vi-CAS-1) was synthesized with vinyl/amino co-modified silicone oil (Vi-ASO-1) and maleic anhydride (MA) as raw materials. Then 0.03 % Vi-CAS-1 in ethyl acetate solution was used as a finishing agent, the performance of Vi-CAS-1 on dacron fabrics was studied, and the effects of carboxyl equivalent, viscosity and the mole ratio of raw materials such as Vi-ASO-1 to MA on the Vi-CAS-1 performance were also investigated carefully. The results shows that, the elasticity and flexibility of fabrics treated by Vi-CAS-1 significantly increase. And when cooperate with the silicone which contains Si-H (PHMS-0.16 %) in application, the compounded Vi-CAS-1 can improve the fabric water-repellency to some extent, as compared with the fabric treated only with Vi-CAS-1.
