6-tetramethyl-4-piperidinylsalicyla-te (TMPS) has been synthesized by ester-exchange reaction between 2
2
6
6-tetra-methyl-4-piperidinol and methylsalicylate. Its physical characteristics including data of nitrogen content
infrared spectrum and NME spectrum were shown. The photos-tabilizing effect of TMPS and Tinuvin 770
PDS on the photodegradation of cis-1
4-polybutadiene has been investigated for comparison. The results observed show that the most effective stabilizer of the three is TMPS. The reason of the good photostea-bilizing effect of TMPS was discussed by fluorescence spectra.
