Abstract:
A process comprising:(i) reacting a polymer, having a functional group, with an activating reagent such that the activating reagent reacts with the functional group, to yield a first reaction product having an activated functional group; and (ii) reacting the first reaction product with a derivatizing reagent such that the derivatizing reagent reacts with the activated functional group, to yield as a second reaction product a derivatized polymer; the activating reagent being a derivative of a compound of the structure â€ƒwherein R1 and R2 are straight-chain, branched-chain or bridged as a carbocycle or a heterocycle; and the functional group is selected from OH, NHR11, SH, OSO3H, SO3H, OPO3H2, OPO3HR11, PO3H2, PO3HR11 and COOH, with R1, R2 and R11 selected such that the process can be carried out in homogeneous phase.
