This invention provides an improved synthesis of polymer conjugates of formula (I),
of agricultural, therapeutic, and food additive compounds. In particular, a process is described for the preparation of conjugates by treating primary or secondary alcohol substituents of active compounds with polymeric nucleophiles using “Mitsunobu” or related reaction conditions.
