| titleOfInvention | Manufacturing method of polyester resin with excellent biodegradability |
| abstract | The present invention aims to obtain a high molecular weight aliphatic polyester having excellent mechanical elongation and excellent biodegradability.Although the aliphatic polyester can be completely decomposed due to its properties, the crystalline polymer has a high molecular weight and a glass transition temperature, but is hard and soluble. Although it has been used mainly for medical use because of the low, the present invention relates to a novel manufacturing method for obtaining a biodegradable injection-molded article, a film having excellent biodegradability and mechanical properties by mixing aliphatic polyester and modified aliphatic polyester. A method for producing an aliphatic polyester obtained by subjecting an acid component and an aliphatic diol component to esterification exchange reaction and then adding a little thermal stabilizer, a lubricant and a UV stabilizer in the presence of a titanium-based or tin-based polycondensation catalyst. Succinic acid or its ester as an acid component Aliphatic polyester (I), terephthalic acid, isophthalic acid, dimethyl terrier synthesized using a mixture of adipic acid or its ester compound as a main component and a single or mixed component selected from 1,4-butanediol and ethylene glycol as diol components Acid components by mixing alone or two or more selected from phthalate, dimethyl isophthalate, and a single or two or more selected from succinic acid, adipic acid, sebacic acid, azelaic acid, or ester compounds of these acids, Blowing film by mixing aliphatic copolymerized polyester (II) obtained by adding small amount of ethylene glycol or 1,4-butanediol as a diol component to a trifunctional or higher polyfunctional compound in a weight ratio of 10:90 to 90:10. A biodegradable polyester characterized by melt extrusion at a temperature of 140 to 180 ° C by molding The method of Le resin. |
