Abstract: 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.

Abstract: 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.

Abstract: The present invention is characterized by introducing isosorbide to a monomer configuration for securing the transparency of a biodegradable polymer as well as providing material having excellent heat resistance and flexibility, As a monomer, a component derived from isosorbide which has a rigid structure is contained by 10-50 mol % of a total diol component, thereby bringing a heat resistance enhancing effect, and enhancing transparency by interfering with crystal formation, and allowing for providing a polymer having excellent flexibility. Thus, the present invention may enable securing stability in usage especially in the packaging area, and enable the heightening of the range of usage and utilization thereof.
