Abstract
This invention is a process to manufacture high quality vinyl aromatic polymer that is essentially free of unreacted vinyl aromatic monomer using retarded anionic polymerization wherein the retardant is insoluble and can be removed from the polymerization at an intermediate stage so that the polymerization can be carried to completion in the absence of the retardant.
