摘要：
According to derivatographic studies, the nature of bulk polymerized PVC decomposition is exothermic and that of suspension-PVC is endothermic. The reason for the difference is that the presence of a pericellular membrane on the surfaces of suspension-PVC grains inhibits the access of oxygen while in the case of bulk polymerized PVC the oxygen has uninhibited access to the grains.
