Polysiloxane gel 6 was obtained from the hydrosilation between 1,5-hexadiene grafted polysiloxane 5 and polysiloxane 4 containing Si-H, which showed good swelling properties for organic solvents such as hexane and toluene. In addition, partially hydrolyzed poly(2-methyl-2- oxazoline) [poly(MeOZO)] 9 was prepared by the alkaline hydrolysis of amide group in poly(MeOZO) 8, which was used as raw materials, together with hexamethylene diisocyanate(HMDI) in the synthesis of poly(MeOZO) gel 7. Interpenetrating Network (IPNs) gel 10 was also obtained from the simultaneous interpenetrating crosslink reactions between 1,5-hexadiene grafte polysiloxane 5/ polysiloxane 4 containing Si-H system and partially hydrolyzed poly(MeOZO) 9 / HMDI system, where the cross influences to each reaction system by two catalysts were not observed. The gel having both hydrophobicity and hydrophilicity was confirmed from swelling properties for hexane/toluene and water, respectively. The blending properties between two polymer components were examined again by the varied glass transition points(Tg''s) in DSC, which were observed to be partially compatible.

1,5-헥사디엔이 그라프트된 폴리실록산과 Si-H 함유 폴리실록산을 하이드로실화 하여 헥산과 톨루엔에 용매 팽윤성이 좋은 폴리실록산 겔을 얻었고 또 한편으로는 부분 가수 분해된 폴리(2-메칠-2-옥사졸린)을 헥사메칠렌-디이소시안네이트와 우레탄 반응을 하여 폴리(옥사졸린) 겔을 얻었다. 아울러 양쪽 반응 시스템을 이용하여 동시 반응으로 상호 침투구조의 겔을 제조하였다. 이때 양쪽 반응 모두는 각각의 촉매에 의해 영향을 받지 않았고 제조된 겔은 헥산/톨루엔과 물의 양쪽 성분에 모두 용매 팽윤성을 보였다. 또 DSC 열분석의 T_g 조사에 의해서는 블렌드 성질이 부분적으로 상용성이 있음을 알수 있었다.
