Abstract: The present invention relates to a process for precipitation polymerization of Alpha -methylstyrene in a hydrocarbon medium in which poly- Alpha -methylstyrene is insoluble or only little soluble. The polymerization is initiated by a finely divided alkali metal which is used together with certain phosphoric acid amides or ethers or mixtures thereof as polymerization accelerators.
Abstract translation: 本发明涉及α-甲基苯乙烯在其中聚-α-甲基苯乙烯不溶或很少溶解的烃介质中的沉淀聚合方法。 聚合是由细分的碱金属引发的，该碱金属与某些磷酸酰胺或其醚或其混合物一起用作聚合促进剂。
