抑制PVC热降解的稳定剂通过各种实验方法已经得到了发展并且已经发现各种二烷基锡化合物特别有效。近来已经证实在稳定剂和聚合物之间发生很多有益的反应。R_2SnX_2稳定剂(R=烷基;X=各种基团,例如硫代乙醇酸烷基酯或马来酸烷基酯)通过同聚合物中不稳定的氯原子互换反应和吸
Stabilizers that inhibit the thermal degradation of PVC have been developed by various experimental methods and various dialkyl tin compounds have been found to be particularly effective. It has recently been demonstrated that many beneficial reactions occur between the stabilizer and the polymer. R 2 Sn X 2 stabilizers (R = alkyl; X = various groups such as alkyl thioglycolates or alkyl maleates) react with unstable chlorine atoms in the polymer and absorb
