β-蒎烯和马来酸酐的反应及产物表征

Reaction of β-pinene with Maleic Anhydride and the Products' Characterization

研究了β-蒎烯和马来酸酐的烯反应、溶剂中自由基共聚反应和本体热共聚反应,得到了β-蒎烯和马来酸酐烯反应产物和共聚产物,并用IR、1HNMR、13CNMR、GPC、DSC进行表征,研究了引发剂浓度、溶剂体系、单体配比、温度等因素对产物的影响。对聚合物进行皂化改性,测量了皂化物浓度对水表面张力的影响。

The ene-reaction, radical copolymerization in the solvent and thermal copolymerization of β-pinene and maleic anhydride had been studied. Reaction products were characterized by FTIR, ^1H-NMR, ^13 C-NMR, GPC and DSC. The influence of initiating agent concentration, solvent, proportion of monomers and temperature on the reaction prodnct were investigated. Saponified modification of the copolymer had been carried on, and the influence of the saponified product＇s concentration on the water surface tension was also discussed.
