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。

Abstract: There are disclosed and claimed novel polyamides characterized by a high transparency together with good mechanical and electrical properties, and especially suitable for the preparation of articles by injection moulding. The polyamides of the invention are prepared by known polycondensation methods from mixtures of 1.3-bis-(aminomethyl)-cyclohexane, optionally partially replaced by 1.4-bis-(aminomethyl)-cyclohexane, and at least one straight-chain aliphatic diamine, and mixtures of at least one aromatic dicarboxylic acid and at least one aliphatic saturated dicarboxylic acid.
