Manufacturing method of biodegradable water-based polyester resin |
| abstract |
The present invention relates to a method for preparing a biodegradable water soluble polyester resin, more specifically relates to a method for preparing a biodegradable water soluble polyester resin using a non-toxic catalyst. The method of the present invention uses a tri- component catalyst consisting of citric acid-Ti-Zn to accelerate a reaction velocity while avoiding use of a prior toxic catalyst. |
