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.
