定向聚合用的ziegkr-Natta型催化剂是由过渡金属卤化物及一、二或三族金属有机化合物组成。二者均具空电子轨道,能与给电子型化合物相络合。如聚合系统中引进给电子型化合物,则将严重影响聚合过程。Badin用三异丁基铝及四氯化钛聚合己烯,并指出,醚、酮及胺等给电子型化合物抑制聚合。Kopotkob在用三乙基铝氯化钛聚 Ziegkr-Natta catalyst for directional polymerization is composed of transition metal halides and one, two or three metal organic compounds. Both have empty electron orbitals that can interact with electron-donating compounds. Such as the polymerization system to the introduction of electronic compounds, it will seriously affect the polymerization process. Badin polymerizes hexene with triisobutylaluminum and titanium tetrachloride and points out that electron-donating compounds such as ethers, ketones and amines inhibit the polymerization. Kopotkob is polymerized with triethylaluminum chloride
