Method for manufacturing biodegradable copolymer by split-injecting aromatic dicarboxylic acid compound |
摘要 |
The present invention relates to a method for manufacturing a biodegradable polyester copolymer, and the method according to the invention comprises the steps of: first esterification-reacting a hydroxy group of an aliphatic dihydroxy compound with a carboxyl group of the aliphatic dihydroxy compound to form an oligomer; secondarily reacting the oligomer that is formed with an aromatic dicarboxylic acid compound; and polycondensation-reacting same in a vacuum state, wherein the dicarboxylic acid compound is sequentially split-injected, and the weight ratio of the oligomer to every injection of the aromatic dicarboxylic acid compound is 5:5 to 8:2. The method according to the present invention efficiently increases solubility of the aromatic dicarboxylic acid thereby increasing reaction speed, and can also reduce side reactions. |
