Aspects generally relate to a temperature responsive polymer, more specifically to a polymer exhibiting an upper critical solution temperature (UCST) in an aqueous solution. In one aspect, a monomer compound includes one or more amide or thioamide groups; one or more ureido or thioureido groups; and one or more ethylenically unsaturated groups. In one aspect, a polymer, such as a homopolymer or a copolymer, is produced by polymerization of the monomer compound. The copolymer is produced by polymerization of the monomer compound and a comonomer, such as a hydrophobic comonomer, a hydrophilic comonomer, a pH responsive comonomer, a light responsive comonomer, and combinations thereof. The polymer exhibits a UCST from about 1° C. to about 100° C. in an aqueous solution at 1 atm.
方面通常涉及温度响应聚合物,更具体地是在水溶液中表现出上临界溶液温度(UCST)的聚合物。在一个方面,单体化合物包括一个或多个酰胺或硫酰胺基团;一个或多个脲基或硫脲基团;和一个或多个乙烯不饱和基团。在一个方面,通过单体化合物的聚合制备聚合物,如均聚物或共聚物。共聚物是通过单体化合物和共聚单体(如疏水性共聚单体、亲水性共聚单体、pH响应共聚单体、光响应共聚单体及其组合)的聚合制备的。在1个大气压下,聚合物在水溶液中表现出从约1°C到约100°C的UCST。
