Abstract
Настоящее изобретение относится к усовершенствованному способу получения биоразлагаемого полимера, который может быть использован для производства упаковочных материалов, который содержит следующие стадии: ферментацию зерна, мелассы и/или подобного углеводного сырья с образованием лактата аммония; затем синтез эфира молочной кислоты из лактата кальция, полученного из культуральной среды, содержащей лактат аммония; последующей поликонденсацией эфира молочной кислоты в присутствии катализатора с образованием олигомера, а затем деполимеризацией олигомера, в результате чего получается лактид, и полимеризацией лактида в полимолочную кислоту в присутствии катализатора.The present invention relates to an improved method for producing a biodegradable polymer that can be used for the production of packaging materials, which comprises the following steps: fermentation of grain, molasses and / or similar carbohydrate raw materials to form ammonium lactate; then the synthesis of lactic ester from calcium lactate, obtained from the culture medium containing ammonium lactate; subsequent polycondensation of lactic ester in the presence of a catalyst to form an oligomer, and then depolymerization of the oligomer, resulting in a lactide, and polymerization of lactide to polylactic acid in the presence of a catalyst.
