Molecular Weight Distribution in Polymers. Polymerization of Isoprene and Butadiene with Metal Organic Compounds

Abstract
Problems connected with the calculation and analysis of molecular weight distributions of polymers obtained by catalytic polymerization were examined. An approximate method of calculation was proposed which is unique in its simplicity and which gives good approximations in the majority of cases of practical interest. Experimental data from a study of samples of polybutadiene and polyisoprene prepared by polymerization in solution by means of butyllithium were considered. The low degree of polydispersity for these polymers was noted in particular.
