The present invention relates to a novel styrenic polymer and to the novel composition comprised of this polymer and a solvent; wherein the styrenic polymer has a polydispersity from 1 to 1.3 and further wherein each polymer chain of the styrenic polymer is capped with one end group of structure 1), wherein, and L is a linking group selected from the group consisting of a direct valence bond, oxy (—O—), carbonyloxy, (—(C═O)—O—), carbonate (—O—(C═O)—O—); L2 is a C-1 to C-20 substituted or unsubstituted alkylene spacer, an arylene spacer or a direct valence bond, R, is hydrogen, a halide, a C-1 to C-20 alkyl moiety, or a C-1 to C-20 alkyloxy moiety, m is an integer from 1 to 3; and (I) represent the direct valence bond attaching the end group 1) to the end of the polymer chain of the styrenic polymer. In another aspect of this invention it pertains to the use of this composition to create self-assembly process.
本发明涉及一种新型苯乙烯聚合物以及由该聚合物和溶剂组成的新型组合物;其中苯乙烯聚合物的多分散性为1至1.3,进一步地,其中苯乙烯聚合物的每条聚合物链都用结构1)的一个末端基团封端,其中,和L是选自直接价键、氧基(-O-)、碳酰氧基、(-(C═O)-O-)、碳酸盐(-O-(C═O)-O-)组成的组的连接基团;L2 是 C-1 至 C-20 取代或未取代的亚烷基间隔物、芳基间隔物或直接价键,R 是氢、卤化物、C-1 至 C-20 烷基或 C-1 至 C-20 烷氧基,m 是 1 至 3 的整数;以及 (I) 代表将端基 1) 连接到苯乙烯聚合物的聚合物链末端的直接价键。本发明的另一方面涉及使用这种组合物来创建自组装过程。
