LONG-CHAIN POLYMETHYLENE HALIDE TELOMERS

摘要

A composition comprises a distribution of telomers of ethylene and at least one fluoroalkyl or perfluoroalkyl halide, the telomers comprising at least one polymethylene segment ( -(CH₂)_n- ) and at least one halomethyl group (-CXH₂) and optionally comprising at least one non-fluorine heteroatom, and the halogen being selected from iodine and bromine; wherein the distribution has a number average ratio of methylene moieties of the polymethylene segment to the halomethyl groups of at least about 15.
