ABSTRACT:
Novel telechelic halogenated polymers of cationically polymerized olefin monomers are formed carrying from 2 to about 6 terminal halogens by a continuous polymerization method. The continuous polymerization method being achieved by feeding to a stirred reactor a first stream composed of a solvent solution of at least one monomer and an inifer and another stream composed of a solvent solution of boron chloride to effect the polymerization of said monomer to a telechelic halogenated polymer product and withdrawing the reaction product from said reactor essentially in amounts equal to that of the sum of the two streams with the feeds to said reactor being simultaneously and continuously fed thereto while maintaining the temperature in the range of minus 10.degree. to minus 80.degree. C.
