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.
