摘要： The invention relates to a polyetherester copolymer composition having a strongly improved UV stability, which is eminently suitable for use in film. The polyestherester copolymer composition according to the invention contains 0.1-10 wt.% activated carbon and 0.05-3 wt.% of a hindered amine light stabilizer (HALS). Preferably, the contents are 0.5-3 and 0.2-1 wt.%, respectively. At a film thickness of 100 νm an increase in the life on the order of a factor 2, relative to the effect of the sum of the individual components, appears to be possible. Preferably, the molecular weight of the HALS is higher than 1500.

摘要： The invention relates to a process for the preparation of a copolyether ester built up of hard polyester segments of repeating units derived from at least one alkylene glycol and at least one aromatic dicarboxylic acid or an ester thereof and soft segments derived from at least one polyalkylene oxide glycol, which comprises polymerization by condensation in the melt of at least one aromatic dicarboxylic acid, at least one alkylene glycol and at least one polyalkylene oxide glycol, in the presence of a catalyst based on a combination of titanium and a bivalent metal in a single compound or several compounds, characterized in that the molecular ratio of Ti : bivalent metal is at most 1.6, preferably at most 1.5. The invention leads to a substantial shortening of the polycondensation time in the melt or a higher degree of polymerization of the copolyether ester. The solid-phase post-condensation can also be shortened substantially. The process is effective in particular for copolyether esters with a high soft segment content and for copolyether esters with soft segments based on polypropylene oxide glycol.
摘要翻译：本发明涉及制备共聚醚酯的方法，所述共聚醚酯由衍生自至少一种亚烷基二醇和至少一种芳族二羧酸或其酯的重复单元的硬聚酯链段和衍生自至少一种聚环氧烷其包括通过在至少一种芳族二羧酸，至少一种亚烷基二醇和至少一种聚环氧烷二醇的熔体中缩合而在基于钛和二价金属的组合的催化剂存在下在单一化合物或几种化合物，其特征在于Ti：二价金属的分子比至多为1.6，优选至多为1.5。本发明导致熔体中缩聚时间的显着缩短或共聚醚酯的较高聚合度。固相后缩合也可以大大缩短。该方法对于具有高软链段含量的共聚醚酯和具有基于聚氧化丙烯二醇的软链段的共聚醚酯是特别有效的。
