摘要： A continuous preparation method of a biodegradable aliphatic/aromatic polyester copolymer includes: performing a first esterification reaction of an aliphatic dihydroxy compound with an aliphatic dicarboxylic acid at a temperature of 185° C. or less; continuously performing a second esterification reaction of a reaction product from the first esterification reaction; continuously performing a first polycondensation reaction of a reaction product from the second esterification reaction to obtain a prepolymer; continuously performing a second polycondensation reaction of the prepolymer to obtain a second polycondensation reaction product having an intrinsic viscosity from about 0.9 dl/g to about 1.0 dl/g; and continuously performing a third polycondensation reaction of the second polycondensation reaction product to prepare the biodegradable aliphatic/aromatic polyester copolymer, wherein the performing of the first esterification reaction or the continuously performing of the second esterification reaction includes adding an aromatic carboxylic acid. The biodegradable aliphatic/aromatic polyester copolymer prepared by control of the intrinsic viscosity of the second polycondensation reaction product may be improved in processibility, film formability, tensile/tearing strength, and blending ability with another polymer resin. Use of a less amount of the aliphatic dihydroxy compound as a starting material may reduce manufacturing costs.
