【Abstract】 rare earth PVC thermal stabilizers are one kind of effective and non toxic stabilizers develop recently.A mathematic method is proposed to study applied model of rare earth stabilizers.The parameters of the curve regression equation represent the disparity of the thermal stabilizers with the type of rare earth stearates.From the IR spectrum and process date,the extra stabilization ability of rare earth stabilizers may be attributed to their conformation transforming effect.更多还原
