SYNTHESIS OF EPOXIDIZED SOYBEAN OIL ACRYLATE OLIGOMER

The synthesis of epoxidized soybean oil acrylate oligomer has been described. The influences of the reaction temperature and time, and catalysts on the esterfication rate of the oligomer were discussed The optimum reaction conditions, through an orthogonal experiment, was finalized as follows: catalyst N,N-dimethyl benzyl amine, reaction temperature and time 115～ 120 ℃/6 hr The structure of the oligomer was characterized by IR spectroscopy
