A biologically active compound can be solubilized by reaction in different sequences to form a derivative carrying the active moiety, a linking group such as an optionally substituted diisocyanate radical, a polyether moiety such as a polyoxyethylene radical, and a terminal group such as a butyl radical, e.g. ##STR1## n=1 to 400. The active materials can be agricultural chemicals, pharmaceuticals, and the like.
