The Mechanisms of Crystallization in Polymers

在制造的加工和制造阶段，有许多变量影响结晶聚合物的物理和机械性能。其中最重要的四个因素是温度、压力、分子量和链的微观结构。在这个项目中，我们正在研究这四种物质对一系列聚合物的协同效应。结晶理论的几个最新的重要进展将被研究的均聚物和共聚物主要是基于聚乙烯，聚丙烯和顺式聚异戊二烯。这一研究将使结晶理论的定量化分析成为可能。它将有助于解开上述变量之间复杂的协同作用。

There are many variables that affect the physical and mechanical properties of crystalline polymers through the processing and fabrication stages of manufacture. Four of the most important are temperature, pressure, molecular weight, and chain microstructure. In this project, the synergistic effects of all four are being investigated for a series of polymers. Several recent important developments in crystallization theory will be investigated for homopolymers and copolymers based principally on polyethylene, polypropylene, and cis-polyisoprene. The research will enable quantitative analysis to be made of crystallization theories. It will help unravel the complicated synergisms of the variables referred to above.
