Biodegradable polyester polymer and method for preparing the same using compressed gases |
| abstract |
The present invention is a polymerization of a biodegradable polymer material, solution polymerization using a compressed gas as a reaction solvent, high molecular weight biodegradable homopolymerized polyester and copolymer in the form of fine powder having a particle size of 0.01 ~ 1000 ㎛ It relates to a method for producing a polyester.n n n The method for preparing a biodegradable polyester of the present invention comprises a monomer selected from the group consisting of compounds including lactide, glycolide, and the like and caprolactone, and mixtures thereof with initiators and organometallic catalysts. And solution polymerization in the presence of the compressor body to polymerize the aliphatic biodegradable polyester and to produce aliphatic biodegradable polyester and copolyester in the form of fine powder or spherical particles. |
