The present invention relates to a preparation method of poly(butylene carbonate-co-terephthalate) resin. According to the preparation method of the present invention, poly(butylene-co-terephthalate) resin can be manufactured using terephthalic acid as a monomer. Also, as the amount of ester residue existing in resin increases, melting point and glass transition temperature of the poly(butylene carbonate-co-terephthalate) resin increase. By adjusting molar ratio of the ester residue, the preparation method of the present invention can adjust physical properties of the resin to have desired properties. The preparation method of poly(butylene-co-terephthalate) resin comprises the steps of: a) performing an esterification reaction of terephthalic acid and 1,4-butanediol; b) performing a transesterification reaction of dimethyl carbonate and 1,4-butanediol; and c) performing a polycondensation reaction by mixing the reaction products obtained from step a) and reaction products obtained from ...

The present invention relates to a novel composite metal oxide catalyst and a method for producing polyester using the same. The metallic bond compound of the present invention has higher catalytic activity than antimonial catalyst and conventional titanium catalyst, readily and stably synthesized, effecting sufficient polymerization activity even with small amount, and can be used as an eco-friendly catalyst for polymerization to produce polyester. Also when producing polyester by using a composite metal oxide of the present invention, phosphor (P) used as a heat stabilizer to reduce pyrolysis during forming hot melt does not lower catalytic activity, and thus can be used much so as to reduce pyrolysis, thereby decreasing yellowing and maintaining high viscosity. Hence, the present invention can be used for producing polyester of excellent physical properties, especially polyethylene terephthalate.
