The present invention relates to a method for preparing a biodegradable polyester copolymer resin with improved hydrolysis resistance. The method according to the present invention comprises the steps of: first reacting an aliphatic dihydroxy compound and an aliphatic dicarboxylic acid compound; and further adding an aromatic dicarboxylate after the first reaction to secondarily react the same, wherein a short-chain alcohol type branching agent is added to a first or a second esterification reaction. The method allows slow esterification by an acid to proceed first, and then applies an aromatic dicarboxylate compound having no acid groups, thereby effectively controlling unreacted products or partially reacted products, which affect the acidity of a product, during the reaction, and thus it is possible to effectively control the acidity even without an excessive amount of excessive BDO, an excessive amount of chain extender or an expensive anti-hydrolysis agent, thereby improving hydrolysis resistance. In addition, it is possible to improve tear strength by minimizing branching agent content used therein.

Abstract
Provided is a production method for a biodegradable resin using a relatively inexpensive compound as an aromatic dicarboxylic acid compound, wherein, during the process of producing a biodegradable resin in the form of an aliphatic-aromatic polyester copolymer, an aliphatic dihydroxyl compound used as a starting material is used in an amount of between 1 and 1.5 equivalent weight with respect to aliphatic and aromatic dicarboxylic acid compounds. The present invention comprises the steps of: causing a hydroxyl group of the aliphatic dihydroxyl compound to undergo a first reaction with a carboxyl group of the aliphatic dicarboxylic acid compound; and causing the residual hydroxyl group of the aliphatic dihydroxyl compound to undergo a second reaction with a carboxyl group of the aromatic dicarboxylic acid compound. The present invention has the advantage that it is possible to produce the aliphatic-aromatic polyester copolymer biodegradable resin by means of an efficient method while not detracting from the mechanical properties of the biodegradable resin.

Abstract
The present invention relates to a biodegradable resin composition. More specifically, what is disclosed relates to: a biodegradable resin composition used as the core material of a draining board which is outstandingly well suited to being produced by extrusion, wherein improvements are made to physical properties such as shrinkage and elastic-recovery-rate reduction by mixing appropriate amounts of a biodegradable resin and an additive for improving processability, thereby improving upon the poor suitability for production which stems from the inherent characteristics of biodegradable resin raw materials, without detracting from the biodegradability which is an inherent characteristic of biodegradable resins. The biodegradable resin composition of the present invention is obtained by mixing from 5 to 60 parts by weight of calcium carbonate, from 1 to 10 parts by weight of a thermoplastic resin and from 0.1 to 5 parts by weight of an active agent, with respect to 100 parts by weight of a biodegradable polymer compound, or by producing an additive in the form of pellets so as to contain from 60 to 90 parts by weight of calcium carbonate, from 5 to 15 parts by weight of a thermoplastic resin and from 1 to 5 parts by weight of an active agent, and mixing from 1 to 50 parts by weight of the additive with 100 parts by weight of the biodegradable polymer compound.
