PROCESS FOR CONTROL OF MOLECULAR WEIGHT DISTRIBUTION IN POLYMERS

This invention relates to a polymerization process for producing polymers with narrow molecular weight distributions. It comprises addition of monomer and initiator to a reaction vessel using a selected monomer feed profile and an initiator feed profile calculated from a polymerization kinetics rela...
