Saccharin was reacted with ethylene carbonate to obtain N-(2-hydroxyethyl) saccharin with which acetic anhydride was reacted to obtain N-(2-acetoxyethyl) saccharin and pyrolysis of N-(2-acetoxyethyl) saccharin in acetone at 480-500℃ gave N-vinylsaccharin.
Polymerization of N-vinylsaccharin was carried out by radical initiators and also copolymerized with acrylonitrile, methylacrylate, and methyl methacrylate by radical initiators.
The composition of poly(acrylonitrile, N-vinylsaccharin) was determined by IR spectroscopy.
By inserting these results into M.Fineman and S.D. Ross equation we determined the values of monomer reactivity ratios.
From Q-e Scheme of Alfrey and Price Q,e values of V-vinylsaccharin have been calculated.
삭카린과 에틸렌 카보네이트를 반응시켜 N - (2-히드록시에틸) 삭카린을 합성하고, 이와 무수초산과의 반응으로 N - (2-아세톡시에틸) 삭카린을 합성하여 이를 480~500℃에서 열분해시켜 N -비닐삭카린을 합성하였다.
라디칼 개시제로 N -비닐삭카린을 중합시키고 아크릴로 니트릴, 메틸아크릴레이트, 메틸 메타아크릴레이트와 공중합시켰다.
폴리(아크릴로 니트릴, N -비닐삭카린)의 조성을 적외선 분광기로 결정하여 MㆍFineman과 S.D.Ross의 식으로 부터 단량체 반응비를 구했다.
Alfrey와 Price의 Q,e체계에서 N-비닐삭카린의 Q,e값을 구했다.
