通过“接枝”方法合成了一系列新型接枝共聚物,在此过程中,首先通过聚醚或聚己内酯二醇与双-N-酰基内酰胺的扩链反应构建聚合物主链。在第一个反应步骤中,苯并恶嗪酮基团被引入到主链中,作为单氨基封端的聚酰胺 12 或聚苯乙烯的接枝位点。扩链和接枝可以在 180-220 °C 的熔体中连续进行,并且具有高选择性。接枝共聚物的形态和热机械行为很大程度上受到接枝侧链类型的影响。具有聚酰胺接枝物的聚合物表现出两相形态,具有微米级的球晶超结构。这些聚合物的拉伸行为由一定的弹性成分表征。相比之下,聚苯乙烯接枝聚合物的相形态要精细得多。对玻璃化转变的强烈影响表明组分之间的相容性得到改善。在聚苯乙烯接枝样品的拉伸测试过程中观察到明显的应变硬化。
A series of new graft copolymers was synthesized by a “grafting to” approach, in the course of which the polymer backbone was build up first by a chain extension reaction of polyether or polycaprolactone diols with bis-N-acyl lactams. During the first reaction step, benzoxazinone groups were introduced into the backbone which served as grafting sites for monoamino-terminated polyamide 12 or polystyrene. Chain extension and grafting could be performed successively and with high selectivity in the melt at 180–220 °C.The morphology and the thermo-mechanical behavior of the graft copolymers were strongly influenced by the type of the grafted side chains. Polymers with polyamide grafts exhibited a two phase morphology with a spherulitic superstructure in the micrometer scale. The tensile behavior of these polymers was characterized by a certain elastic component.In contrast, the phase morphology of a polystyrene grafted polymer was much finer. A strong influence on the glass transitions revealed improved compatibility between the components. Pronounced strain hardening was observed during the tensile test of polystyrene grafted samples.
