Abstract

The need for titanium compounds for homogeneous catalysis is gradually increasing due to their non-toxic properties and catalytic activity. In this study, a new titanium (IV) salicylate complex was obtained capable of catalyzing the polymerization of ε-caprolactone and D,L–lactide with benzyl alcohol as co-initiator. The catalyst was investigated by different methods like MALDI, NMR-spectroscopy and XRD. This new titanium complex has proven to be an effective catalyst for ROP reactions at 120 °C. This catalyst has shown significant efficiency due to the high molecular weight of the resulting polymer (M_w ~ 80,000) and a narrow dispersity (M_w/M_n < 1.3).

低毒环保水杨酸钛催化剂催化ε-己内酯与D， l -丙交酯开环聚合

由于钛化合物的无毒特性和催化活性，对其均相催化的需求逐渐增加。本研究制备了一种新型水杨酸钛配合物，该配合物可以催化ε-己内酯和D， l -丙交酯在苯甲醇的催化下聚合。采用MALDI、nmr、XRD等方法对催化剂进行了表征。这种新型钛配合物已被证明是120°C下ROP反应的有效催化剂。由于所得聚合物分子量高（Mw ~ 80000），分散性窄（Mw/Mn < 1.3），该催化剂表现出显著的效率。

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
