| titleOfInvention | Process for producing polyester resin excellent in biodegradability |
| abstract | The objective of the present invention is to obtain a high molecular weight aliphatic polyester excellent in mechanical strength and biodegradability. Although the aliphatic polyester is completely decomposable by its nature, the crystalline polymer has a high molecular weight and a high glass transition temperature, The present invention relates to a novel production method for obtaining a degradable article and film having excellent biodegradability and mechanical properties by mixing an aliphatic polyester and a modified aliphatic polyester, A process for producing an aliphatic polyester in which a monomer of an acid component and an aliphatic diol component is subjected to ester exchange reaction and then a condensation polymerization reaction is obtained by adding a little heat stabilizer, a lubricant and a UV stabilizer in the presence of a titanium- or tin- In the method, succinic acid or its esters An aliphatic polyester (I) synthesized by using a leucine compound and an adipic acid or an ester compound thereof and a diol component in combination with 1,4-butanethiol or ethylene glycol, and terephthalic acid or sebacic acid as an acid component, (II) by a combination of ethylene glycol or 1,4-butanediol as a diol component, and melt-extruding the mixture at a temperature of 140 to 180 DEG C by blowing film molding A method for producing a polyester resin having excellent properties. |
