THE EFFECTS OF TEMPERATURE UPON RADICAL COPOLYMERIZATION OF 2, 2, 6, 6-TETRAMETHYL PIPERIDINYL METHACRYLATE WITH STYRENE
温度对4-甲基丙烯酸2,2,6,6-四甲基哌啶醇酯与苯乙烯自由基共聚活性的影响

The effects of temperature on the reactivity ratios are different in various solvents. The complex constants for monomers and solvents have been determined by NMR spectroscopy. The values of enthalpy and entropy for monomers interacting with solvents have been calculated. In accordance with these results, the dependance of monomers reactivity radio on the polymerization temperature has been discussed.
