  Substituted malonic acid derivatives and their use as stabilizers

  摘要：

  来自4-羟基和4-氨基多烷基哌啶和在中心碳原子上用有机残基（最好是烷基，酯基烷基或膦烷基）取代的羟基苯甲酸的酯和酰胺是有机聚合物的优秀稳定剂，特别是对于聚烯烃。它们不仅可以保护聚合物免受光降解，还可以保护聚合物免受热氧化降解。这些化合物可以通过将相应的取代马来酸衍生物进行羟基苯甲基化来制备。双马来酸衍生物可以通过与甲醛反应来从单马来酸衍生物中获得。

  A process for producing a cellulose ester film that is produced by a melt casting method using no solvent at film formation, and that attains reduction of bright spot foreign matter, excelling in planarity, and that attains reduction of staining, excelling in dimensional stability. It is also intended to provide such a cellulose ester film, a polarizing plate and a liquid crystal display unit. There is provided a process for producing a cellulose ester film, characterized by forming into a film a material containing a cellulose ester and an ester compound of 1 to 7.5 distribution coefficient obtained by condensation of a polyhydric alcohol and an organic acid of the general formula: (1) according to a melt casting method.

  Esters and amides from 4-hydroxy-and 4-amino-polyalkylpiperidines and hydroxybenzylmalonic acids substituted at the central carbon atom with an organic residue, preferably alkyl-, esteralkyl- or phosphonoalkyl-groups, are excellent stabilizers for organic polymers, especially for polyolefins. They protect the polymers as well against light degradation as against thermo-oxidative degradation. The compounds can be prepared by hydroxybenzylation of the corresponding derivatives of substituted malonic acids. Bis-malonic acid derivatives may be obtained from the monomalonics by reaction with formaldehyde.
