Abstract
The effect of the stearate stabilizers on the dehydrochlorination of CPE was investigated by Congo Red Method.The results showed that the dehydrochlorination temperature of CPE tended to increase and the initial dehydrochlorination time tended to extend as the stearate level increased;the dehydrochlorination temperature was higher by using lead stearate and barium stearate and its initial time was longer;and the dehydrochlorination temperature of CPE was higher by using lead stearate/barium stearate,lead stearate/calcium stearate,or calcium stearate/barium stearate with blending ratios of 1∶1,2∶1 and 1∶3 respectively,and the initial dehydrochlorination time was longer when the above blending ratios changed to 3∶1,2∶1 and 1∶1 respectively.
