Polyhydroxybutadiene compounds are storage stabilized against reactivity changes by incorporating therein an effective amount of a di or triphenyl phosphine compound of the formula
wherein each x is hydrogen, a halogen or an alkyl or alkoxy group having from 1 to 10 carbon atoms and y is an alkyl group having from 1 to 10 carbon atoms or an aryl group which may be substituted with a halogen or an alkyl or alkoxy group having from 1 to 10 carbon atoms.
通过在聚羟基
丁二烯化合物中加入有效量的二苯基或
三苯基膦化合物,可稳定该化合物的反应性变化,其中每个 x 为氢、卤素或具有 1 至 10 个碳原子的烷基或烷氧基,y 为具有 1 至 10 个碳原子的烷基或可被卤素或具有 1 至 10 个碳原子的烷基或烷氧基取代的芳基。
