Abstract
Polymerizations catalyzed by very finely divided lithium. The process is characterized in using lithium having an average particle diameter of less than 2.mu. and preferably of 0.1.mu. or less as a polymerization initiator. The process permits .alpha.-.omega. dilithic oligomers to be obtained.
