Process for the preparation of poly - hidroxialcanoatos, poly 3-hydroxybutyrate, and mixture of biodegradable polyester

摘要

Process for the preparation of polihidroxialcanoatos, poly 3-hydroxybutyrate, and mixture of biodegradable polyester.The invention relates to a process for the preparation of polihidroxialcanoatos by polymerization of lactones of general formula I, in which the substituents and the index n have the designation cited in the report describing, in the presence of at least one catalyst of formula (II) l ~ 1 ~ m ^ ^ x ^ ^ ~ M ~, in that the substituents and indices have the designation cited in the report description.The invention also relates to poly - 3 - hidroxibutiratos have a new profile of properties and are accessible for the first time by said process and mixtures of biologically degradable polyester based on so-called poly 3 - hidroxibutiratos.
