ABSTRACT:
The alkyllithium initiated preparation of terminally functional polymers in high yield is accomplished by first capping a macromolecular polymer with an alkylene sulfide prior to terminating the molecule with a halogenated compound containing a polymerizable moiety. The resulting macromolecular monomers are useful in the preparation of graft copolymers by copolymerizing the macromolecular monomers with monomers copolymerizable therewith.
