Abstract

The invention discloses a preparation method and application of a macromolecular polymerization catalyst. The preparation method comprises the following steps: adding manganese acetate to 1,4-butanediol, mixing, stirring, adding titanium isopropoxide, continuously stirring for 0.5-1 hour at 220-240 DEG C, adding stannous octoate, and continuously stirring for 1-2 hours to obtain the catalyst. The preparation method of the macromolecular polymerization catalyst is simple, easy to operate and mild in the reaction conditions and can be put into the continuous industrial production favorably.

Description

technical field [0001] The invention belongs to the field of macromolecular synthesis, and relates to a preparation method of a macromolecule polymerization catalyst, and also relates to the application of the catalyst. Background technique [0002] High-molecular polymers refer to high-molecular-weight (usually up to 10-106) compounds composed of many identical and simple structural units linked repeatedly through covalent bonds. Polymers polymerized from one monomer are called homopolymers, such as polyvinyl chloride, polyethylene, etc. Polymers formed by the copolymerization of two or more monomers are called copolymers, such as vinyl chloride-vinyl acetate copolymers. A polymer catalyst is a polymer that catalyzes a chemical reaction. Enzymes in living organisms are natural polymer catalysts with high activity and high selectivity, but because they are water-soluble, their industrial applications are limited. Therefore, immobilized enzymes that are insoluble in water h...
