PROCESS FOR PRODUCING A BIO-BASED POLYETHYLENE TEREPHTHALATE (PET) POLYMER, ENTIRELY FROM BIO-BASED MATERIALS

摘要

The invention relates to a process for producing a bio-based polyethylene terephthalate (PET) polymer, from at least one terephthalate compound obtained from at least one bio-based material, and at least one monoethylene glycol compound obtained from at least one bio-based material,;Said process comprising the polymerization of the terephthalate compound and of the monoethylene glycol compound in the presence of at least one crystallization retarding compound,;Said process being characterized in that the crystallization retarding compound is obtained from at least one bio-based material.;The invention also relates to a bio-based PET polymer obtained by said process.;Preferably, the process further comprises processing the bio-based PET polymer into a bio-based product such as a bio-based container or a bio-based packaging. The invention also relates to said bio-based product.
