Abstract

3-bis[3-(1-methoxy-2-hydroxypropoxy)propyl]polysiloxane was prepared by the equilibrium copolymerization of octamethyl cyclotetrasiloxane(D

) and 1

3-bis[3-(1-methoxy-2-hydroxypropoxy)propyl]tetramethyldisiloxane. The effects of reaction temperature

reaction time

catalyst type and amount of the catalyst on the reaction had been researched. The results suggest that the optimal synthesis conditions were that the reaction was carried out at 65℃ for 24 hours using concentrated sulfuric acid at a mass fraction of 0.3% of the reaction substance as catalyst.And then the reaction has the highest conversion rate. The product was characterized by FTIR and

H NMR.
