| titleOfInvention | Polyester resin composition and its manufacturing method |
| abstract | The present invention relates to a polyester resin composition and a method for manufacturing the same, in particular, a polyester resin composition that solves the difficulty of practical use as a trash bag or shopping bag, etc. caused by the lack of tear strength in the conventional aliphatic polyester and It relates to a manufacturing method. SUMMARY OF THE INVENTION An object of the present invention is to provide a high molecular weight polymer having biodegradability as well as sufficient mechanical properties such as melt viscosity required for various molding processes such as injection molding, blow molding, and film molding and practically required tear strength of the molded article. To provide an ester resin composition and a method for producing the same, in order to achieve the above object, in the present invention, (1) aliphatic (including cyclic aliphatic) dicarboxylic acid (or anhydride thereof) containing succinic acid, and (2) 1 (3) Functional groups of 0.1 to 30% by weight based on aliphatic (including cyclic aliphatic) glycols containing any one or more selected from among 4-4-butanediol and ethylene glycol and functional groups, and hydroxyl and amine groups. Any one or two selected from a condensation reaction, an esterification reaction, and a transesterification reaction in the presence of a monomer each including one or two or more The number average molecular weight obtained by the polycondensation reaction after the phase reaction is 30,000 to 70,000, the weight average molecular weight is 160,000 to 600,000, the melting point is 61 to 120 ℃, the melt viscosity (190 ℃, 2,160 g) is 0.1 to 50 Polyester resin composition and production method are provided. |
