6 tetramethyl-4-piperidinylmethacrylate) and 2
2
6
6 tetramethyl-4-piperidinol were compared. It was shown that
the copolymer stated above can accumulated more quantity of stable free radical than another one under same condition.In the experiments of quenching effect for fluorescence of pyrene
the effect of copolymer is similar to the low molecular compound.
