In this study, novel α-truxillic and β-truxinic acid-based, bio-derived diesters have been developed as internal donors for preparing Ziegler-Natta (ZN) catalysts. Impacts of these bio-derived diesters were investigated on the chemical composition, the morphology, the mode of adsorption, and the propylene polymerization performance of the catalysts in comparison to the most widely used fourth-generation catalyst containing dibutyl phthalate. The molecular structures of the diesters and the particle morphology of the catalysts were preserved in the catalyst preparation. The bio-derived diesters afforded ZN catalysts with a reasonable activity and stereospecificity in propylene polymerization along with similarly broad molecular weight distribution (MWD) as the phthalate-based catalyst. Another promising feature of the catalysts was an opposite hydrogen response in terms of expansion of MWD upon the addition of H₂.

在这项研究中，新型的基于α-truxillic和β-truxinicacid的生物衍生二酯已被开发为制备Ziegler-Natta（ZN）催化剂的内部供体。与最广泛使用的含邻苯二甲酸二丁酯的第四代催化剂相比，研究了这些生物衍生的二酯对催化剂的化学组成，形态，吸附方式和丙烯聚合性能的影响。在催化剂制备中保留了二酯的分子结构和催化剂的颗粒形态。生物衍生的二酯为ZN催化剂在丙烯聚合中提供了合理的活性和立体选择性，以及与邻苯二甲酸酯基催化剂相似的宽分子量分布（MWD）。₂。
