Abstract
소수성 polydimethylsiloxane(PDMS)과 친수성인 poly(2-hydroxyethylmethacrylate)(PHEMA)의 공중합체를 합성하여 여러가지 용매의 팽윤도를 측정하였다. 그 결과 PHEMA의 용해도 파라미터(δ)가 26(J/cm3)1/2인 것으로 나타났다. PHEMA의 함량이 많은 공중합체에는 δ값이 큰 에탄올의 함유율이 높았으며, PDMS의 함량이 많은 경우 δ값이 작고 극성인 tetrahydrofuran의 함유율이 높았다. 또한 용매의 δ값이 클수록 PDMS의 함량의 증가와 함께 용매 함유율은 증가하였다. 모델 의약으롤 사용된 crystal violet(CV)의 흡수거동을 조사한 결과 CV의 흡수율은 PHEMA 단일 중합체보다 PDMS가 함유된 공중합체일 때 더 큰 값을 나타내었다. 공중합체 중의 PDMS 함량이 증가하면 CV의 흡수율은 감소하였다.

Polydimethylsiloxane(PDMS)-co-poly(2-hydroxyethyl methacrylate)(PHEMA) was prepared and the degree of swelling of solvents into the polymers was examined. It was confirmed that the solubility parameter of PHEMA homopolymer is 26 (J/cm3)1/2. Ethanol was significantly absorbed into copolymers containing large amount of PHEMA, while tetrahydrofuran was effectively absorbed into copolymers containing large amount of PDMS. Absorption of polar solvents into the copolymers were increased with the increase of PDMS content. The model drug, crystal violet (CV), was more absorbable into PDMS-HPEMA copolymers than PHEMA homopolymer. Absorption of CV was decreased with the increase of PDMS content of the copolymers.
