Abstract
Способ переработки полиэтилентерефталата в мелкодисперсный порошковый материал, который включает растворение полиэтилентерефталата в органическом растворителе в присутствии стабилизатора гидролитической деструкции или без него, на протяжении 10-25 минут при атмосферной давлении и температуре 190- с последующим диспергированием и центрифугированием полученной дисперсии, при этом как ПЭТФ применяют товарный или вторичный ПЭТФ, как стабилизатор - ароматический моно- или поликарбодиимид, как растворитель ПЭТФ - комбинированный пластификатор (диметилфталат, диэтилфталат, дибутилфталат или их смеси во всех соотношениях, или регенерат указанного пластификатора) и дополнительно применяют поверхностно-активное вещество (ПАВ) - Твин 80 при следующем соотношении ингредиентов, % масс.:
