摘　　要：阐述了聚合过程对重力的敏感性和微重力下的聚合机理,介绍了微重力条件下聚合过程的一些研究成果,同时对未来的空间微重力条件下聚合物材料的发展前景进行了分析。Under microgravity condition, the gravity has weak effect on objects, also the lack of convection lead to the formation of more perfect structures. The research of polymers under microgravity condition has attracted considerable attentions recently. In this paper, gravitationally sensitive mechanisms of polymerization process are discussed, and the progress in polymerization process under microgravity condition is introduced. Finally, the prospect on polymerization process under mierogravity condition is also presented.
