在聚合物合成过程和聚合物凝固过程中，聚合物分子量和聚合物颗粒尺寸的大小、分布和聚合物聚集态结构强烈依赖于重力，本文分增重力、减重力和微重力三部分阐述了近年来重力对聚合物形成影响研究概况，重点介绍了微重力下聚合物的一些研究成果，并指出了今后的发展方向。 In the process of polymer synthesis and polymer solidification, the size and distribution of polymer molecular size and polymer particle size strongly depend on the gravity of the aggregated state of the polymer. In this paper, three parts including gravity, weight loss and microgravity are described in recent years Based on the research of the influence of gravity on the formation of polymer, some research results of polymer under microgravity are introduced emphatically, and the direction of future development is pointed out.
