Process of radial polymerisation of vinylidene chlorate and such polymers

摘要

A method of preparing halogenated polymers by radical polymerization employing one or more ethylenically unsaturated monomers one at least of which is halogenated, molecular iodine and one or more free radical generators (diazo compounds, peroxides, dialkyldiphenylalkanes) by charging a reactor with at least a fraction of the three compounds, initiating the reaction and then introducing any balance of them. Independent claims are included for (1) halogenated polymers with a number average mol.wt. above 1.0x10 4> and a polydispersity index below 1.60, (2) for a method of preparing block copolymers of which at least one block is a halogenated polymer employing one or more ethylenically unsaturated monomers and one or more of the claimed halogenated polymers, (3) for block copolymers comprising one or more blocks of the claimed polymer, (4) for articles produced using one or more polymers prepared by the claimed method or claimed polymers .
