Plastics are moving into the 21st century! A new generation of materials will be designed, not only in the shape and form of their components, but right down at the level of the molecules themselves. UK groups in chemistry, physics, maths and engineering have been working to find out the best way to join up the long string-like molecules of plastics like polyethylene (PE) to help smooth the path of their processing. In the hot melted state their flow is not only liquid but also elastic. This feature needs to be carefully controlled by molecular design. Several US groups have been working with PE made by new catalysts that may be able to deliver the ideal molecular structures. This proposal is to join up these two leading collaborations to fast-track the new materials.

塑料正在进入21世纪的世纪！新一代的材料将被设计出来，不仅是在其组成部分的形状和形式上，而且在分子本身的水平上。英国的化学、物理、数学和工程小组一直在努力寻找最好的方法，将聚乙烯（PE）等塑料的长串状分子连接起来，以帮助其顺利加工。在热熔融状态下，它们的流动不仅是液态的，而且是弹性的。这种特性需要通过分子设计来仔细控制。几个美国研究小组一直在研究由新催化剂制成的聚乙烯，这些催化剂可能能够提供理想的分子结构。该提案旨在将这两个领先的合作项目结合起来，以快速跟踪新材料。
