The Dow Chemical Company has developed a new family of propylene-ethylene (P/E) copolymers with narrow molecular weight distributions and broad crystallinity distributions.  These copolymers allow exceptionally high filler loadings while maintaining a low viscosity and therefore, good processability. Industrial studies have demonstrated that they can incorporate filler loadings as high as 80 wt% and remain easily processable. In comparison, LDPE and traditional P/E copolymers filled as low as 30 40 wt% can have viscosities that are too high to process. This work, performed at Concordia University in partnership with The Dow Chemical Company, will be a comprehensive study of particulate-filled polymers and will provide important understanding of the relationships between viscoelasticity, composite microstructure, polymer molecular structure and interfacial phenomena.  This research project will benefit Canada's manufacturers of polyolefins and plastics and suppliers of particulate fillers.  It will also provide an important, fundamental contribution to polymer science.

陶氏化学公司开发了一种新的丙烯-乙烯（P/E）共聚物，具有窄的分子量分布和宽的结晶度分布，这类共聚物在保持低粘度和良好加工性能的同时，还具有极高的填料含量。工业研究表明，它们可以包含高达80重量%的填料负载，并保持易于加工。相比之下，LDPE和传统的P/E共聚物填充低至30 - 40重量%，可以具有粘度太高，无法处理。这项工作，在康考迪亚大学与陶氏化学公司合作进行，将是一个全面的研究颗粒填充聚合物，并将提供重要的理解之间的关系粘弹性，复合材料微观结构，聚合物分子结构和界面现象。该研究项目将有利于加拿大的聚烯烃和塑料制造商以及颗粒填料供应商。它还将提供一个对聚合物科学做出了重要的基础性贡献。
