    摘要： A composition of the invention includes a polymer component which consists essentially of an asymmetric telechelic polymer having a boron-containing head group. These asymmetric telechelic polymers can also have halogen tail groups. The end group functionalities make these polymers extremely useful because, for example, the functionalities facilitate subsequent elaboration of the polymer. A method of forming the composition includes forming a reaction mixture which consists essentially of an olefin, a Lewis acid, and a base which will react with essentially all protic impurities in the reaction mixture, thereby preventing protic initiation during polymerization of the olefin. The reaction mixture is exposed to conditions which cause the olefin to react to form an initiator in situ which can cause polymerization of additional olefin to form a polymerized olefin consisting essentially of a telechelic polymer. In another embodiment, the initiator has the structure BX.sub.2 --[CH.sub.2 --C(CH.sub.3).sub.2 ].sub.n A, where "n" is at least one, "X" is a halogen, and "A" is a leaving group.

    摘要： 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.
