Embodiment Construction

[0013] Add 1g of supported zinc dicarboxylate catalyst into a 0.5L autoclave equipped with a stirrer, connect the entire reaction system to a vacuum system, and then vacuum-dry the autoclave that has been placed in the pre-weighed catalyst at 80°C for 24h . After drying, drop to room temperature, inject a certain proportion of propylene oxide and cyclohexane oxide into the autoclave, and feed carbon dioxide, heat, start stirring, adjust the pressure of carbon dioxide to 5.2Mpa, make the reaction system between 5.2Mpa and React at 60°C for 40 hours. After the reaction was over, carbon dioxide was released, and the viscous mixture in the kettle was taken out. This mixture was dissolved in chloroform, and the catalyst in the system was removed with 5% dilute hydrochloric acid solution, and washed three times with distilled water. Then adjust the chloroform solution of the obtained copolymer to a certain concentration, and then use ethanol to precipitate, and the obtained white ...

Abstract

The present invention belongs to the field of high-molecular material, in particular, it relates to a polymethylethylene-cyclohexylene carbonic ester material and its preparation method. Said invention adopts carbon dioxide, epoxy propane and epoxy cyclohexane, under the action of high-effective catalyst load zinc binary carboxylate to synthesize degradable plastic polymethylethylene-cyclohexylene carbonic ester. The epoxy cyclohexane has rigid lexatomic ring, can be used as third monomer and added into copolymerization reaction of epoxy propane and carbon dioxide. Said invention utilizes the regulation of epoxy cyclohexane content in the reaction so as to obtain the ternary copolymer on whose main chain the different cyclohexylene contents can be contained. Said ternary copolymer has high mechanical strength and thermal property.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polymethylethylene-cyclohexylene carbonate material and a preparation method thereof. Background technique [0002] Carbon dioxide is recognized as the main gas that causes global warming, and it is estimated that carbon dioxide causes about 66% of the greenhouse effect. Since the 20th century, with the advancement of science and technology, people's living standards have been continuously improved, and the white pollution and greenhouse effect brought about by industrial development have also continuously deteriorated the living environment of human beings. Polymerizing carbon dioxide in the atmosphere with epoxy compounds into degradable polymer plastics can effectively alleviate the increasingly serious problems of greenhouse effect and white pollution. Carbon dioxide is a cheap and high-quality carbon source, but due to its inertness, how to efficiently utilize carbon diox...
