Description
Technical Field
The invention relates to the field of olefin polymerization organic metal catalysts and olefin coordination polymerization, in particular to a vanadium complex catalyst containing a large steric hindrance phenol oxygen ligand and a preparation method and application thereof.
Background
The application fields of polyolefin materials in modern industrial production and daily life are wide, and the output of the materials is the most global. Olefin polymers not only provide a lot of convenience for people's daily life, but also drive the development of many industries in the industries of optical instruments, chemistry, medical instruments, electronic devices, insulating materials, and the like. But due to the non-polarity and low surface energy, the dyeing property, the adhesive property, the hydrophilicity, the antistatic property and the compatibility with other polar high polymers or inorganic fillers are poor, so that the expansion of the application range is limited. And the performance of the polymer can be obviously improved by introducing a polar group with rich reactivity into a polyolefin chain structure to prepare the functionalized polyolefin.
