| 摘 要： | 研制的 SG010-C 和 SG010-X 型催化剂,对氧气敏感性好,用于乙烯均(共)聚制 L 型热熔胶。在聚合过程中,通过改变催化剂的结构和氢调控制聚合物的熔体指数、分子量分布、颗粒度、熔点等。可一步生产出热熔胶粉末、不经粉碎分级。

“IL”Type Hot Melt Adhesives |
| |
| Abstract: | The“L”type hot melt adhesives are prepared by homo- or co-polymerizationof ethylene using SG010-C and SG010-X catalysts which are sensitive to hydro-gen,The melt index,molecular weight distribution,particle size and meltingpoint of the adhesives can be controlled by the rate of addition of hydrogen andby modifying the structure of the catalyst.The powdery adhesives are directlyproduced in one step without crushing. |
