Abstract

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.

摘要

聚烯烃是消费品的主要组成部分。在这里，壳聚糖这种可从大量渔业废弃物中提取的生物聚合物，通过喷雾干燥成型为微球状载体，以促进乙烯聚合。采用确定性筛选设计有效地优化合成步骤。对所制备的催化剂进行乙烯聚合测试，并使用各种微观和光谱技术评估甲基铝氧烷（MAO）负载量和生成孔隙率的影响。
