摘要 甲基丙烯酸-N,N-二甲氨基乙酯及其聚合物的热和pH响应性陈双基,薛梅,李福绵(北京大学分校化学系北京100083)(北京大学化学系北京100871)关键词聚(甲基丙烯酸-N,N-二甲氨基乙酯),热响应性,pH响应性,功能高分子材料近年来,关于热响应... Dimethylaminocthyl methylacrylate (DMAEMA) and its polymer exhibit thermo-sensitive response. The phase separation of their aqueous solution occurs abfruptly when the raising temperature reachs certain degrees. Thus, the temperature of phase separation of 10%,5.0%,2.5%,1.0%(DMAEMA) solution are 40.2,42.5,44.5,52.4℃ respectively. The thermosensitive phase separation also depends on the acidity of solution. The temperature and pH dependence swelling behavior o f slightly crosslinked P(DMAEMA) in water was studied. The adsorption of methyl orange for P(DMAEMA) at different temperature was investigated. P(DMAEMA) can lie expected as a functional material with thermal and pH-response.
