    • The invention relates to a method for producing a bio-PET polymer comprising the following steps: Step A) providing at least one diacid compound, comprising a terephtalate compound; Step B) providing at least one diol compound, comprising monoethylene glycol; wherein - at least one of the terephtalate compound and/or the monoethylene glycol is obtained from at least one bio-based material, and - at least one of the diacid compound and/or the diol compound further comprises at least one crystallization retarding compound; and Step C) copolymerizing a mixture of the diacid compound and the diol compound to obtain a bio-PET polymer comprising diacid units and diol units, comprising up to 7.5 mol% of unit(s) corresponding to the at least one crystallization retarding compound, based on the total number of moles of diacid units contained in the bio-PET. The invention also relates to a method for producing a bio-PET packaging element, comprising the following steps: performing the method described above; and Step D) converting the bio-PET into the bio-PET packaging element.
    • 本发明涉及生产生物PET聚合物的方法,其包括以下步骤:步骤A)提供至少一种包含对苯二甲酸酯化合物的二酸化合物; 步骤B)提供至少一种二醇化合物,其包含单乙二醇; 其中 - 对苯二甲酸酯化合物和/或单乙二醇中的至少一种由至少一种生物基材料获得,并且 - 所述二酸化合物和/或所述二醇化合物中的至少一种还包含至少一种结晶阻滞化合物; 和步骤C)使所述二酸化合物和所述二醇化合物的混合物共聚以获得包含二酸单元和二醇单元的生物PET聚合物,其包含对应于所述至少一种结晶阻滞化合物的至多7.5摩尔%的单元, 基于生物PET中包含的二酸单元的总摩尔数。 本发明还涉及生产生物PET包装元件的方法,包括以下步骤:执行上述方法; 和步骤D)将生物PET转换成生物PET包装元件。
