| 摘要 |
Copolymer on 4-acryloyloxy-2,2,6,6-tetramethyl-piperidine and 4-hydroxy-3,5-di-terc.butylbenzylacrylate base with formula I is prepared, by polymerizating of 4-acryloyloxy-2,2,6,6- -tetramethylpiperidine with 4-hydroxy-3,5-di-terc. butylbenzylacrylate in hydrocarbon solvent, advantageous in benzene or toluene at temperature 60 to 70 degrees of Celsius by presence 2,2'-azobisizobutyronitrile as radical initiator during 24 hours.
