Preparation method of hindered amine light stabilizer containing hindered phenol structure

The invention relates to a preparation method of a compound shown as a formula I. Under the action of a supported catalyst, a compound shown as a formula Ia reacts with a compound shown as a formula Ib to obtain the compound shown as the formula I. The method has the beneficial effects that the catalyst can be recycled and is non-corrosive and avoids the generation of a large amount of alkaline wastewater and is a green and environment-friendly route suitable for industrial production.

ULTRAVIOLET ABSORBER FOR SYNTHETIC RESIN AND SYNTHETIC RESIN COMPOSITION CONTAINING THE SAME

The present invention relates to an ultraviolet absorber for synthetic resins composed of a triazine compound represented by the general formula (I) shown below (wherein R represents an alkyl group having 1 to 4 carbon atoms, n is 0 or an integer of up to 2, and X represents a group selected from the consisting of group (a) to (d) shown below) (wherein R1 represents an aliphatic group having 5 to 60 carbon atoms, which is an alicyclic group, an alkyl group having an alicyclic group at the terminal or in the chain thereof, an alkyl group having a branch, or a linear alkyl group, depending on the number of carbon atoms; R2 represents an alkyl group having 1 to 18 carbon atoms or a (poly)alkyleneoxyalkyl group; R' represents an aliphatic diyl group having 5 to 60 carbon atoms; R and n have the same meanings as those described in the general formula (I) above).
