摘要： AS A NEW MATTER COMPOSITION OF, A CELLULAR RUBBER BASED ON 1,2-POLYBUTADIENE AND A PROCESS FOR PREPARING SAME. A VERY VALUABLE CELLULAR RUBBER HAVING A FINE AND UNIFORM CELLULAR STRUCTURE CAN BE OBTAINED BY A SINGLE VULCANIZING AND FOAMING STEP WHEN POLYBUTADIENE CONTAINING A LARGE NUMBER OF 1,2-CONFIGURATION UNITS IS USED AS THE STARTING ELASTOMER.

摘要： A process for producing cyclic compounds of conjugated diene polymers which comprises bringing at least one polymer selected from the group consisting of conjugated diene polymers and copolymers having unsaturated bonds in the main chain or side chain into contact with a catalyst composed of at least one compound selected from the group consisting of organoaluminum halides represented by the general formula R2AlX or R3Al2X3 (wherein R is alkyl group having one to 12 carbon atoms and X is a halogen) and at least one organic halogenated compound.
