摘要

聚烯烃是消费产品的主要组成部分。在这里，壳聚糖是一种生物聚合物，可以从大量的渔业废物中提取，它被塑造成一个微球载体，使用喷雾干燥来促进乙烯聚合。采用确定性筛选设计，有效地优化了合成步骤。对生成的催化剂进行了乙烯聚合测试，并使用各种显微和光谱技术评估了MAO负载和生成的孔隙率的影响。

Chitosan microsphere-supported catalysts: design, synthesis and optimization for ethylene polymerization†

Polyolefins are the main building blocks for consumer products. Here, chitosan, a biopolymer that can be derived from abundant fishery waste, is shaped as a microspheroidal support using spray drying to facilitate ethylene polymerization. Definitive screening design was used to optimize synthesis steps efficiently. The generated catalysts were tested for ethylene polymerization, and the effects of MAO loading and generated porosity were assessed using a variety of micro- and spectroscopic techniques.
