Summary:1,170,687. Polymerisation catalyst MARUZEN PETROCHEMICAL CO., Ltd. and TOYO RUBBER INDUSTRY CO. Ltd. 6 Feb., 1967 [10 Feb., 1966; 27 Jan., 1967], No. 5620/67. Heading B1E. [Also in Division C3] A polymerisation catalyst for epoxides comprises the reaction product of dialkyl zincs or organo aluminium compounds with a nitrocompound containing a nitro group adjacent to a carbon with an active hydrogen. The catalyst is prepared in an inert diluent at -78‹C to room temperature and may be subjected to an ageing treatment before use.
