| titleOfInvention | Method of continuous obtaining of polyesters |
| abstract | FIELD: chemistry. n SUBSTANCE: claimed invention relates to method of continuous obtaining of polyesters. Described is method of continuous polymerisation with opening of ring of cyclic ester monomers with formation of aliphatic polyesters based on monomers of cyclic ester, which includes the following operations: a) continuous supply of cyclic ester monomer and polymerisation catalyst into continuous stirred loop reactor, reactor working under efficient for polymerisation conditions with formation of prepolymerised reaction mixture with polymerisation degree between 40% and 90% at temperature from 100 to 240°C; b) continuous discharge of prepolymerised reaction mixture from continuous stirred reactor and continuous supply of prepolymerised reaction mixture into plug flow reactor, with plug flow reactor working under conditions of polymerisation, under which reaction mixture is polymerized to polymerisation degree of at least 90%, with formation of polymer at temperature from 100 to 240°C; c) continuous discharge of polymer from plug flow reactor. n EFFECT: obtaining high quality polyesters from the point of view of molecular weight, structure of polymer chain, colour and content of residual monomer. n 14 cl, 1 ex |
