  Hindered amines based on various 2,2,6,-tetra-alkylated nitrogen-containing heterocyclic moieties wherein the hindered nitrogen atom on the ring is substituted with O-acyl, O-carbamoyl or O-carbonate substituents and the 4-position of the ring is substituted with a variety of groups, are effective as light stabilizers in diverse substrate systems. Some of them are new compounds.

  Pre-exfoliated natural or synthetic, modified or unmodified layered materials are prepared by mixing layered materials with one or more plastics additives selected from the group consisting of ultraviolet light absorbers, hindered amine light stabilizers, antioxidants, colorants, flame retardants, antimicrobials and fatty acid additives and melt extruding the mixture. The layered materials are for example modified or unmodified layered silicate clays. The galleries of the layered materials in the mixtures are expanded to a level of less than full exfoliation. The melt extruded mixtures of layered materials and additives are highly useful to prepare polymer nanocomposites.

  预剥离天然或合成、改性或未改性分层材料的制备方法是将分层材料与一种或多种塑料添加剂混合，这些添加剂选自紫外线吸收剂、受阻胺光稳定剂、抗氧化剂、着色剂、阻燃剂、抗菌剂和脂肪酸添加剂组成的组，然后对混合物进行熔融挤压。分层材料可以是改性或未改性的分层硅酸盐粘土。混合物中分层材料的廊道被扩展到小于完全剥离的程度。分层材料和添加剂的熔融挤压混合物非常适用于制备聚合物纳米复合材料。
