    The field of new compounds and synthesis methods thereof are related, and particularly to a structure of a steric hindrance adjustable weak base light stabilizer and a preparation method and application thereof. According to the innovative light stabilizer, a steric hindrance thereof is adjusted by establishing substituent generating the steric hindrance around nitrogen atoms; moreover, an electronegativity of the nitrogen atom can be influenced by adjusting a distance of a polar group, so that an alkalinity or a nucleophilicity of the nitrogen atom is adjusted. A desired effect is obtained by adjusting a steric hindrance and a nucleophilic property or an alkalinity where the nitrogen atom is located, so that an application range of the innovative light stabilizer is widened, and the innovative light stabilizer is suitable for PC, polyester, PVC and other slightly acidic or certain electrophilic polymer materials to serve as a light stability protecting aid.
    新化合物和合成方法领域相关,特别是一种结构可调节立体位阻的弱碱光稳定剂及其制备方法和应用。根据这种创新的光稳定剂,通过在氮原子周围引入产生立体位阻的取代基来调节其立体位阻;此外,通过调节极性基团的距离可以影响氮原子的电负性,从而调节氮原子的碱性或亲核性。通过调节氮原子所在位置的立体位阻、亲核性或碱性,可以获得所需的效果,从而扩大创新光稳定剂的应用范围,使其适用于PC、聚酯、PVC等微酸性或某些亲电性聚合材料,作为光稳定保护助剂。
  • Substituted malonic acid derivatives and their use as stabilizers
    申请人:Ciba-Geigy Corporation
    公开号:US04198334A1
    公开(公告)日:1980-04-15
    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.
    4-羟基和4-氨基多烷基哌啶与中心碳原子上有机残基(优选为烷基、酯基烷基或膦酸酯基)取代的羟基苯甲酸酯和酰胺是有机聚合物的优秀稳定剂,特别是对聚烯烃。它们能够保护聚合物免受光降解和热氧化降解的影响。这些化合物可以通过对取代马来酸的相应衍生物进行羟基苄化来制备。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。
