    Abstract: CONJUGATED DIENES ARE POLYMERIZED BY A NES CATALYST SYSTEM WHICH PERMITS CONTROL OF THE MOLECULAR WEIGHT AND GIVES A MORE EASILY PROCESSED PRODUCT. THIS CATALYST SYSTEM COMPRISES (1) AN ALKALI METAL, NAMELY LI, NA, K, CS AND RB, MODIFIED WITH (2) AN ALKOXIDE OF K, NA AND LI, IN WHICH THE ALKOXIDE HAS 1-10 CARBON ATOMS. THE DIENE POLYMERS PRODUCED BY THIS PROCESS HAVE CONTROLLABLE MOLECULAR WEIGHTS IN THE RANGE OF 5,000-1,000,000, PREFERABLY 100,000-500,000, BROAD MOLECULAR WEIGHT DISTRIBUTION, GLASS TRANSITION TEMPERATURES HIGHER THAN NORMALLY OBTAINED, A HIGH DEGREE OF BRACHING, AND ARE MORE EASILY PROCESSED IN THE PRODUCTION OF RUBBER AND OTHER COMPOSITIONS FOR COMMERCIAL USE.
