两亲性共聚物是通过丙烯酸2-羟乙酯与丙烯酸丁酯的自由基共聚合成的，其反应性比表明反应性实际上相等。含有少于 30 mol% BA 的共聚物可溶于水并在水溶液中表现出 LCST。研究发现，这些共聚物与聚丙烯酸在水溶液中的相互作用导致形成通过氢键和疏水相互作用稳定的互聚物复合物。这种相互作用受到溶液 I pH 值的显着影响，并导致共聚物的温度响应行为发生变化。
Amphiphilic copolymers have been synthesised by free radical copolymerisation of 2-hydroxyethyl acrylate with butyl acrylate, the reactivity ratios of which indicate practically equal reactivity. The copolymers containing less than 30 mol-% of BA were soluble in water and exhibited a LCST in aqueous solutions. It was found that the interaction between these copolymers and poly(acrylic acid) in aqueous solutions resulted in the formation of interpolymer complexes stabilised by hydrogen bonds and hydrophobic interactions. This interaction was significantly affected by solution I pH and led to modification of the temperature-responsive behaviour of the copolymers.
