Abstract

This research was to investigate the polyester preparation using waste ethylene glycol (EG) generated from the wastepaper pretreatment process. Waste EG was obtained from using EG five times repeatedly in the pretreatment of wastepaper. The hydroxyl value of the waste EG was 441 mg KOH/g and its composition was 0.68% cellulose, 6.5% hemicellulose, 6.1% lignin, and 86.7% EG. Maleic acid was used as carboxylic acid. The effect of reaction temperature and time except carboxyl group/hydroxyl group ratio on the crosslinkage of the prepared polyester was marginal. Citric acid, lithium hydroxide and dicumyl peroxide were used as additive or catalyst to enhance the crosslinkage of polyester. Among them, 10% of citric acid was found to be most effective. The crosslinkage was 86% when the polyester was prepared at an optimum condition such as $130^{\circ}C$ and 15 minutes, 1.5 of C/H ratio, and 10% of citric acid, and its insoluble percentage in boiling water for 6 hours was 47%. The weight loss of the prepared polyester was approximately 40% when it was buried in damp soil for 5 months, indicating that it is readily biodegradable. This results can provide some information for future development of wastepaper pretreatment by organic solvent.
