  • Novel telechelic polymers, block copolymers and processes for the preparation thereof
    Patent number: 4276394
    Abstract: Novel telechelic halogenated polymers of cationically polymerizable olefin monomers are formed carrying from 2 to about 6 terminal halogens. The telechelic halogenated polymers are formed by reacting the monomer with an initiator transfer agent, carrying at least two tertiary halogens, and under cationic polymerization conditions. Additionally, novel thermoplastic elastomer block copolymers are formed from these telechelic halogenated polymers by reacting the latter with vinyl aromatic monomers in the presence of a coinitiator.
