摘要：

The kinetics of the ene reaction of stearyl acrylate with polybutadiene oils in the temperature range of 180 to 220-degrees-C is described. The ene reaction was found to be of pseudo 1 st order with respect to stearyl acrylate because of the excess of polybutadiene double bonds. The rate constants correlate with the reaction temperature according to the Arrhenius law. The products show typical side-chain crystallization, which has a strong influence on the viscosity and the autoxidation kinetics of the unsaturated polymeric backbone. Just below the crystallization temperature of the side chains the network formation by autoxidation is much slower than above the melting point.
