Verfahren zur Faellungspolymerisation von alpha-Methylstyrol
摘要
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.
