The present invention relates to new stabilizers of polymers and co-polymers of vinyl chloride corresponding to the general formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which are the same or different, represent: R.sub.1 = a hydrogen atom or a branched- or straight-chain alkyloxy group containing from 1 to 12 carbon atoms, R.sub.2 = a hydrogen atom, a branched-or straight-chain alkyl group containing from 1 to 3 carbon atoms or a branched- or straight-chain alkyloxy group containing from 1 to 12 carbon atoms, R.sub.3 and R.sub.5 = a hydrogen atom, a hydroxy group, a branched- or straight-chain alkyl group containing from 1 to 3 carbon atoms or a branched- or straight-chain alkyloxy group containing from 1 to 12 carbon atoms, R.sub.4 = a hydrogen atom, a hydroxy group, a branched- or straight-chain alkyl group containing from 1 to 3 carbon atoms or a branched- or straight-chain alkyloxy group containing from 2 to 12 carbon atoms, R.sub.6 = a hydrogen atom or a branched- or straight-chain alkyl group containing from 1 to 3 carbon atoms, With the proviso that one at least of the substituents R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 does not represent a hydrogen atom or an alkyl radical and that one at least of the substituents R.sub.4, R.sub.5 and R.sub.6 does not represent a hydrogen atom.
本发明涉及与聚氯乙烯的新稳定剂相对应的通式的聚合物和共聚物的新稳定剂:其中R.sub.1、R.sub.2、R.sub.3、R.sub.4、R.sub.5和R.sub.6,它们相同或不同,表示:R.sub.1 = 氢原子或含有1至12个碳原子的支链或直链烷氧基团,R.sub.2 = 氢原子,含有1至3个碳原子的支链或直链烷基团或含有1至12个碳原子的支链或直链烷氧基团,R.sub.3和R.sub.5 = 氢原子,羟基,含有1至3个碳原子的支链或直链烷基团或含有1至12个碳原子的支链或直链烷氧基团,R.sub.4 = 氢原子,羟基,含有1至3个碳原子的支链或直链烷基团或含有2至12个碳原子的支链或直链烷氧基团,R.sub.6 = 氢原子或含有1至3个碳原子的支链或直链烷基团,但须至少有一个取代基R.sub.1、R.sub.2、R.sub.3、R.sub.4、R.sub.5和R.sub.6不表示氢原子或烷基基团,且至少有一个取代基R.sub.4、R.sub.5和R.sub.6不表示氢原子。
