  • Anionic polymerization process
    Patent number: 6657028
    Abstract: A batch process for the anionic polymerization of a styrenic monomer is described. The process brings together a liquid saturated hydrocarbon diluent, an ether promoter, an organolithium initiator and a styrenic monomer in such a way so as to maintain the reaction mixture at or below about 55° C. and so that the amount of organolithium initiator employed is in the range of about 1 to about 10 mol %, based upon the total amount of styrenic monomer to be added. Favorable polydispersity and molecular weight polymer characteristics are obtained.
