通过可控/活性自由基乳液共聚合，将苯乙烯-丙烯酸甲酯共聚物的链序设计成V型梯度序列。这种特殊设计的链序列赋予了这种常见的共聚物多形状记忆能力。在温度的刺激下，共聚物可以从三个或更多个先前编程的临时形状顺序恢复到其永久形状。
The chain sequence of a poly (styrene-co-methyl acrylate) copolymer is designed to form a V-shaped gradient sequence via controlled/living radical emulsion copolymerization. This specially designed chain sequence gives this common copolymer the capacity of multishape memory. The copolymer can sequentially recover to its permanent shape from three or more previously programmed temporary shapes with the stimulus of temperature.
