NOVA Chemicals is involved in the development of novel polymerization catalysts allowing the generation of polyolefins with long branches. In order to determine the specific branching characteristics they need to achieve desirable physical properties, they require model polymers with well-defined branching characteristics. We propose a path for the synthesis of model branched polyethylene, based on the copolymerization of a monomer with selected macromonomers having a terminal unsaturation (to form the long branches), and followed by hydrogenation of the branched polymer structure. This Engage Grant will focus on the preparation of the target macromonomers as the first and most critical step of the synthetic process.

NOVA化学公司参与开发新型聚合催化剂，以生产具有长支链的聚烯烃。为了确定实现理想物理性能所需的特定支化特性，它们需要具有明确支化特性的模型聚合物。我们提出了一种合成模型支化聚乙烯的途径，基于单体与具有末端不饱和度的选定大分子单体（以形成长支链）的共聚，然后对支化聚合物结构进行氢化。该Engage Grant将专注于目标大分子单体的制备，作为合成过程的第一步和最关键的一步。
