POLYMERIC PHOTOSTABILIZERS CONTAINING TWO KINDS OF PHOTOSTABILIZING GROUPS Ⅱ. SYNTHESIS AND PHOTOSTABILITY OF COPOLYMERS OF 2,2,6,6-TETRAMETHYL-4-PIPERIDINYL METHACRYLATE AND β-HYDROXY-γ-(ORTHO-HYDROXY BENZOXY) PROPYL METHACRYLATE

Received Date: 8 January 1986

A new kind of photostabilizers, eopolymer of 2, 2, 6, 6-tetramethyl-4-piperidinyl methacrylate and β-hydroxy-γ-(ortho-hydroxy benzoxy) propyl methacrylate, has been synthesized. The spectral behaviors of these copolymers were studied in detail. In the presence of salicylyl group a strong absorption in the region of 280—330 nm could be observed, and an unusual Stoke's shift appeared in the fluorescence spectrum excited by 310nm. The photostabilization ability of these copolymers in the process of photodegradation of cis-poly(butadiene)was studied.Results indicated that these compounds possess excellent photostabilization ability.
