Abstract
Novel halostyrene telechelic polymers having from 2 to about 6 terminal halogens, halostyrene-polyether, block copolymers having ABA type structures in star type structures, depending on the number of halogen terminii in the starting halostyrene block, and a process for their formation is described. The halostyrene polymers are formed by the initiator transfer agent or inifer polymerization method; while the polyether block is polymerized by silver catalysis of monomers such as tetrahydrofuran. The polymers and copolymers have good flame resistance.
