摘要： There are provided a resin composition for foaming including a biodegradable resin and a foamed article made thereof. The resin composition for foaming according to the present invention includes an ethylene-vinyl acetate resin, a biodegradable polyester resin containing a monomer of a double bond compound, a cross-linking agent, a co-crosslinking agent, a filler, and a foaming agent. In the resin composition, the double bond in the biodegradable polyester resin can be chemically cross-linked to the ethylene-vinyl acetate resin by a cross-linking agent, so that a compatibility with the ethylene-vinyl acetate resin can be improved, processability (mold releasability) during a mixing and melting process can be improved, and a foaming property and a mechanical property of a foamed article can be remarkably improved.

摘要： There is provided a method of preparation for a biodegradable co-polyester resin with improved hydrolysis resistance, the method including performing a primary esterification reaction between an aliphatic dihydroxy compound and an aliphatic dicarboxylic acid compound, and performing a secondary transesterification reaction with addition of an aromatic dicarboxylate after the primary esterification reaction, in which a short chain alcohol-type branching agent is added to the primary esterification reaction or to the secondary transesterification reaction. In the method of the present invention, the slow esterification reaction caused by acid is performed first and the aromatic dicarboxylate compound without acidity is added thereto, thereby efficiently controlling a non-reactant or a partial-reactant affecting an acid value of a product during the reaction, so that an acid value can be controlled and hydrolysis resistance can be improved without using an excessive amount of expensive BDO, an reaction of an excessive amount of a chain extender, or using an expensive anti-hydrolysis agent. Further, by minimizing an amount of the branching agent used herein, tear strength can be improved.
摘要翻译：提供了一种制备具有改善的耐水解性的可生物降解的共聚酯树脂的方法，所述方法包括在脂族二羟基化合物和脂族二羧酸化合物之间进行初级酯化反应，并通过加入芳族化合物进行二次酯交换反应在主酯化反应中加入短链醇型支化剂，或者进行二次酯交换反应。在本发明的方法中，首先进行由酸引起的慢酯化反应，并向其中加入无酸性的芳族二羧酸酯化合物，从而有效地控制影响产品的酸值的非反应物或部分反应物反应，从而可以控制酸值，并且可以提高耐水解性，而不需要使用过量昂贵的BDO，过量的扩链剂的反应或使用昂贵的抗水解剂。此外，通过使本文使用的支化剂的量最小化，可以提高撕裂强度。
