Propylene glycol을 첨가제로 사용하여 HEMA (2-hydroxyethyl methacrylate)와 교차결합제인 EGDMA(ethylene glycol dimethacrylate) 그리고 개시제인 AIBN(azobisisobutyronitrile)을 사용하여 공중합 하였다. 생성된 고분자의 물리적 특성을 측 정한 결과, 함수율 37.06 ~ 38.71%, 굴절률 1.492 ~ 1.432, 가시광선 투과율 89.4 ~ 91.5%, 인장강도 0.1416 ~ 0.2302 kgf 그리고 접촉각의 경우 38.60 ~ 53.53o 범위의 분포를 나타내었다. 따라서 propylene glycol을 첨가한 콘택트렌즈 재료의 경우, 기본적 인 콘택트렌즈의 물성을 만족하였으며 함수율의 큰 변화를 나타내지 않으면서도 습윤성과 인장강도를 증가시키는 결과를 보여주었다.

HEMA (2-hydroxyethyl methacrylate), EGDMA (ethylene glycol dimethacrylate) and propylene glycol was copolymerized in the presence of AIBN (azobisisobutyronitrile) initiator in a mould. The physical properties of the contact lens were measured. The water content of 37.06 ~ 38.71%, refractive index of 1.492 ~ 1.432, visible transmittance of 89.4 ~ 91.5%, tensile strength of 0.1416 ~ 0.2302 kgf, and contact angle of 38.60~53.53° were obtained. Therefore, the contact lens material produced using propylene glycol as an additive satisfied the basic physical properties required for contact lenses application. It is interesting to note that an increase in wettability and tensile strength while having no significant changes in water content.
