Cleaving and replacing thio control agent moieties from polymers made by living-type free radical polymerization
A method of free radical polymerization and for cleaving a thio group from the resulting polymer is provided. The method comprises forming a mixture of one or more monomers, at least one free radical source and a control agent, wherein the control agent comprises a thio moiety. The mixture is polymerized, and the resulting polymer is mixed with a free radical source, and optionally an addition fragmentation agent under cleavage conditions. The thio moiety on the polymer is replaced with a group of interest.
