친수성기를 함유한 polysiloxane 막의 합성

Abstract

Si-H결합에 CH₂=CH-R을 부가하는 방법을 이용하여 친수성기를 함유하는 실란단량체인(2,3-epoxypropoxy)propyldiethoxymethylsilane(EDMS)과 acetoxypropyldiethoxymethylsilane(ADMS)을 합성하였다.

EDMS와 ADMS를 이용하여 poly(2,3-dihydroxypropoxy)propylmethylsiloxane과 poly(3-hydroxypropyl)methylsiloxane을 얻었다. poly(2,3-dihydroxypropoxy) propylmethylsiloxane은 42.4%의 함수율을 나타냈으며 poly(3-hydroxypropyl)methylsiloxane은 물에 용해?臼눼?.

Using the methods of addition for Si-H bond to unsaturated hydrocarbons, (2,3-epoxypropoxy)propyldiethoxymethylsilane(EDMS) and acetoxypropyldiethoxymethylsilane(ADMS) were synthesized. Poly(2,3-dihydroxypropoxy)propylmethylsiloxane and poly(3-hydroxypropy)methylsiloxane were synthesized from EDMS and ADMS, respectively. Water content of poly(2,3-dihydroxypropoxy)propylmethylsiloxane was 42.4%, and poly(3-hydroxypropyl)methylsiloxane was soluble in water.
