Abstract

The present invention relates to a method for inhibiting acetaldehyde, carboxyl end groups, and diethylene glycol chemicals in case Mg2B2O5 compound in ratio of 0.2% is added into PET during injection. The objective of the present invention is to prevent the formation of harmful chemicals such as acetaldehyde (AA), COOH end group content (COOH), diethylene glycol (DEG) which increase with chemical degradation of PET material in the period passing from raw material to final product.
