| Abstract: | The photostabilising effect of polymeric hindered amine stabilizer (styrene-2,2,6,6-tetrame-thyl-4-piperidinyl mathacrylate copolymer) have been investigated in rhodamine 6G photosensitized degradation of cis-1,4-poly (butadiene). It have been found that the polymeric hindered amine stabilizer have properties of quenching singlet oxygen, decomposing hydroperoxide and scavenging macro-radicals produced during photooxidation and effectively protects cis-1,4-poly (butadiene) against singlet oxygen oxidation.The mechanism of photostabilization has been discussed. |
