| description | The invention relates to a divisional application of a Chinese invention patent application with an application number of 202011250638.2 and an invention name of a structure of a steric hindrance-adjustable weak-base light stabilizer and a preparation method and application of the steric hindrance-adjustable weak-base light stabilizer. The invention belongs to the field of new compounds and synthesis methods thereof, and particularly relates to a steric hindrance adjustable weak base light stabilizer and a preparation method and application thereof. According to the innovative light stabilizer, the steric hindrance of the light stabilizer is adjusted by establishing the size of substituent groups generating steric hindrance around nitrogen atoms in the structural general formula, in addition, the electronegativity of the nitrogen atoms can be influenced by adjusting the distance of polar groups, and therefore the alkalinity or nucleophilic performance of the light stabilizer is adjusted. The desired effect is |
