摘要：

Aluminum chloride is shown to react with ethanol at room temperature to form a product or product mixture that can act as a thermal stabilizer for poly(vinyl chloride). The stabilization is revealed by a decrease in the rate of thermal dehydrochlorination at 190 degrees C and by a reduction in the average length of the resulting polyene sequences. These observations clarify a report by previous workers in which the same effects were said to ensue from an aluminum-chloride-promoted addition reaction of the polyenes with HCl. A possible mechanism of action is suggested for the stabilizer formed from aluminum chloride and ethanol. (C) 1997 Elsevier Science Limited.
