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.

摘要： The present invention relates to a method for using a combination of two kinds of thermal stabilizers in a production process in order to improve the thermal stability of biodegradable polyester resins, and to biodegradable polyester resin produced therefrom. In said method, two kinds of thermal stabilizers improve thermal stability by acting complementarily with each other. Thus, a high temperature reaction is possible, and due to an increase in the reactivity, the reaction time is shortened and the molecular weight is increased. In addition, the obtained resin can provide high quality products, since the acid value thereof is reduced to improve the hydrolysis resistance thereof, and the chromaticity thereof is enhanced to thereby be capable of preventing a yellowing phenomenon of the final product.

摘要： The present invention relates to a biodegradable resin having outstanding colouring properties, and provides a resin composition which does not give rise to problems such as reduced strength due to colouration. The composition of the present invention, suggests that a PBSAT resin is used as a biodegradable resin, and colouration is performed with same. Also, at this time, the colourant can be mixed in the form of masterbatch. In the present invention, the resin composition is used in the production of various products, in particular monofilament yarn produced via spinning and a fishing net manufactured from same is provided. Fishing nets such as the above are advantageous in that such fishing nets can be realized in various colours in accordance with customer requirements and satisfy the required strength and, after use, degrade naturally in seawater and so do not give rise to problems like environmental pollution.
