一种用于光稳定剂的含多受阻哌啶基的受阻胺化合物及其制备方法
摘要：
本发明公开了一种用于光稳定剂的含多受阻哌啶基的受阻胺化合物，其由通式(I)表示。本发明的受阻胺化合物具有多受阻哌啶基，因而将其用作光稳定剂时，增强了耐热性、相容性和耐抽提性。本发明还公开了一种用于光稳定剂的含多受阻哌啶基的受阻胺化合物的制备方法。其中R1，R2为H或C1-C4烷基；R4为H、C1-C8烷基或苄基；R5为H、O自由基、-OH、-Cl、-CH2CN、C1-C8烷基、C1-C8烷氧基、被羟基取代的C1-C8烷氧基、C5-C12环烷氧基、C3-C6链烯基、被苯基取代的C1-C3烷基。
摘要（英）：

The invention discloses a multi-hindered piperidyl-containing hindered amide compound used for a light stabilizer, which is represented by a general formula (I). The hindered amide compound of the invention is provided with a plurality of hindered piperidyls; and therefore, heat resistance, compatibility and extraction resistance are enhanced when the hindered amide compound is used as the light stabilizer. The invention also discloses a preparation method for the multi-hindered piperidyl-containing hindered amide compound used for the light stabilizer. In the general formula described in the specification, R1 and R2 are Hs or alkyls of C1 to C4; R4 is an H, an alkyl of C1 to C8, or a phenmethyl; and R5 is the H, an oxygen radical, -OH, -Cl, -CH2CN, the alkyl of C1 to C8, an alkoxyl of C1 to C8, a hydroxyl-substituted alkoxyl of C1 to C8, a cycloalkyloxy of C5 to C12, an alkenyl of C3 to C6, or a phenyl-substituted alkyl of C1 to C3.
