Abstract

A process for preparing butanediol polysuccinate able to be fully biodegradated includes such steps as adding butanediol and butanedioic acid to reactor, esterifying reacting at 150-200 deg.C, and vacuum polycondensating at 200-280 deg.C under the existance of catalyst. It is a thermoplastic resin with 100,000 of mass average molecular weight and better mechanical performance.

Description

technical field

[0001] The invention belongs to the field of methods for preparing polyester by condensation polymerization, in particular to polybutylene succinate prepared from butanediol and succinic acid as monomers, which are fully biodegradable polyesters prepared by condensation polymerization Alcohol ester method. Background technique

[0002] "White pollution" is a worldwide issue. In today's deteriorating environment, how to solve the contradiction between the use of plastic products and environmental damage (such as the pollution of waste plastic film, waste foam packaging, plastic bags, etc. to the environment) is becoming more and more important. Therefore, the research and application of various "environmentally friendly materials" has received extensive attention, and the development and application of fully biodegradable plastics has become a research hotspot worldwide.

[0003] Polybutylene succinate is a fully biodegradable polyme...
