Abstract:
A compound characterized by the following the general formula: where SU represents a sugar unit in a cellulosic backbone, L is an optional linker, Y is a control agent site from which a polymer may propagate during a free radical polymerization reaction, a is in the range of from about 3-80, b is in the range of from about 1-25, c is 0 or 1, and d is 1-3, wherein Y is characterized by at least one of the following formulas: where Z is any group that activates the C&boxH;S double bond towards a reversible free radical addition fragmentation reaction and Râ€³ is selected from the group consisting of optionally substituted hydrocarbyl and heteroatom-containing hydrocarbyl, and the group is attached to the linker or sugar unit via either the Z or Râ€³ groups; or(2)â€”Iâ€”Oâ€”NR5R6, wherein I is an initiating fragment and each of R5 and R6 is independently selected from the group of hydrocarbyl, substituted hydrocarbyl, heteroatom containing hydrocarbyl and substituted heteroatom containing hydrocarbyl; and optionally R5 and R6 are joined together in a ring structure.
