Method for producing polyester polyol with increased functional group using polyethylene terephthalate chip |
| abstract |
The present invention is a method for producing a polyester polyol which is a raw material of polyurethane by the depolymerization reaction by glycolysis of PET chip, prepared by adding pentaerythritol or sorbitol (sorbitol) It relates to a polyester polyol having an increased functional group and a polyurethane using the same. More specifically, the present invention relates to a method for preparing a polyester polyol having increased functional groups such as compressive strength, flexural strength, and thermal conductivity when a polyurethane is manufactured using a polyester polyol having an increased functional group. |
