通过异氰化物单体（1）与Ni（ii）引发剂络合物反应制备聚苯乙烯-b-聚异氰丙氨酸（2-噻吩-3-基-乙基）酰胺（PS-PIAT）二嵌段共聚物，所述Ni（ii）引发剂络合物由通过原子转移自由基聚合（ATRP）或阴离子聚合（AP）获得的聚苯乙烯胺（PS40 NH 2）制备。结果发现，光学纯1的聚合遵循单体浓度的一级动力学，并导致形成不溶性嵌段共聚物，而光学混合物1的聚合速率被延迟，并产生更好地溶解的嵌段共聚物。此外，PS-PIAT聚合物囊泡的PS-块是由AP制备的聚合物囊泡比PS-块是由ATRP制备的聚合物囊泡更稳定，如由组合的浊度和动态光散射（DLS）测量的聚集体解决方案。
The diblock copolymer polystyrene-b-polyisocyanoalanine(2-thiophene-3-yl-ethyl)amide (PS-PIAT) was prepared by reacting the isocyanide monomer (1) with a Ni(ii) initiator complex prepared from polystyrene amine (PS40NH2), either obtained by atom transfer radical polymerization (ATRP) or anionic polymerization (AP). It was found that polymerization of optically pure 1 followed first-order kinetics in monomer concentration and resulted in the formation of insoluble block copolymers, whereas the rate of polymerization of optical mixtures of 1 was retarded and yielded block copolymers that were better soluble. Furthermore, PS-PIAT polymersomes of which the PS-block was prepared by AP were more stable than polymersomes of which the PS-block was prepared by ATRP, as was indicated by combined turbidity and dynamic light scattering (DLS) measurements on the aggregate solutions.
