Continuous preparation method of biodegradable aliphatic/aromatic polyester copolymer |
| abstract |
A continuous preparation method of a biodegradable aliphatic/aromatic polyester copolymer comprises: performing a first esterification reaction of an aliphatic dihydroxy compound with an aliphatic dicarboxylic acid at a temperature of 185 ° C or lower; continuous a second esterification reaction of the reaction product from the first esterification reaction; a first polycondensation reaction of the reaction product from the second esterification reaction is continuously carried out to obtain a prepolymer having a weight average molecular weight of from about 6,900 to about 14,000 Performing a second polycondensation reaction of the prepolymer to obtain a second polycondensation reaction product; and continuously performing a third polycondensation reaction of the second polycondensation reaction product to prepare the biodegradable aliphatic/aromatic poly An ester copolymer wherein the first esterification reaction or the continuous second esterification reaction comprises the addition of an aromatic carboxylic acid. |
