Abstract
The present invention relates to a method for preparing an olefin-unsaturated carboxylic acid copolymer and an olefin-unsaturated carboxylic acid copolymer prepared by the method. The catalyst used in the process comprises a diimine metal complex of formula I. The spherical and/or spheroidal polymer prepared by the preparation method has good prospect in industrial application.
Description
Technical Field
The invention belongs to the field of preparation of high molecular polymers, and particularly relates to a method for preparing an olefin-unsaturated carboxylic acid copolymer.
Background
The polyolefin product has low price, excellent performance and wide application range. Under the condition of keeping the excellent physical and chemical properties of the original polyolefin, polar groups are introduced into polyolefin molecular chains by a chemical synthesis method, so that the chemical inertness, the printing property, the wettability and the compatibility with other materials can be improved, and new characteristics which are not possessed by raw materials are endowed. Although polar monomers can be directly introduced into polyolefin chains by high-pressure radical copolymerization, the method requires high-temperature and high-pressure conditions, and is high in energy consumption and expensive in equipment cost.
As a preparation technology of polymers at normal temperature and normal pressure, coordination catalytic copolymerization has attracted extensive attention due to its remarkable effects in reducing energy consumption, improving reaction efficiency and the like. The catalyst participates in the reaction process, so that the activation energy of the copolymerization reaction of the olefin monomer and the polar monomer is greatly reduced, and the functional polymer with higher molecular weight can be obtained at lower temperature and pressure. Currently, only a few documents report the use of transition metal complexes to catalyze the copolymerization of olefins and unsaturated carboxylic acids. However, in the prior art, no matter which method is adopted for polymerization reaction, the obtained polymer is viscous massive solid, and is easy to scale in polymerization equipment, thereby bringing difficulties to the transportation, solvent removal, granulation and the like of the polymer.
