Copolymerization of 2-Hydroxyethy1 methacrylate and N-(2-hydroxyethy1) methacry1 amide
Abstract
2-Hydroxyethyl methacrylate (HEMA)와 N-(2-hydroxyethyl)methacryl amide (HEMAA)를 60.1℃에서 共重合시켜 單量體의 反應性比를 구하여 다음과 같은 값을 얻었다.

γ₁=1.17 γ₂=0.39

또한 Alfrey-Price식을 利用하여 HEMMA의 Q및 e값을 계산하여 각각 0.814, 1.071의 값을 얻었다. 重合體속의 單量體의 평균서열길이를 통계적으로 계산한 결과 두 단량체의 농도가 같을 때는 HEMA의 平均길이는 2.1이고 HEMAA는 1.5이었다.
The monomer reactivity ratios determined at 60.1℃ for the free radical copolymerization of 2-hydroxyethyl methacrylate(HEMA) and N-(2-hydroxyethyl)methacryl amide(HEMAA) are:

γ₁=1.17 γ₂=0.39

The values of Alfrey-Price's Q and e of HEMAA were found to be 0.814 and 1.071, respectively. By the statistical analysis for the monomer sequence in polymer, the mean sequence length of HEMA is 2.1 when the mole fraction of each monomer is 0.5, but for the HEMMA is 1.5.
