AMIDOXIME DERIVATIVES, PROCESSES FOR THE PREPARATION THEREOF AND USES THEREFOR ABSTRACT OF THE DISCLOSURE The invention provides amidoxime derivatives of the general formula Image wherein Rl is an alkyl group of 1 to 8 carbon atoms, phenyl, a heterocyclic ring structure of 5 to 8 atoms containing one or more nitrogen or oxygen atoms or combinations thereof or a bicyclic condensed ring system optionally containing at least one heterocyclic ring which groups may each be optionally substituted. R2 is a mono or bicyclic heterocyclic radical containing at least two nitrogen atoms which radical is also optionally substituted. R3 and R4 are independently H, or an alkyl of 1 to 4 carbon atoms or one, but not both, is Image and the other, H, wherein R5 or R6 are alkyls oF 2 to 5 carbon atoMs optionally substituted by Rl, or a phenyl optionally substituted by Rl or R5 or R6 is combined with Rl to jointly form cyclic imidoximes or imidedioximes. The in- vention also provides processes for the preparation of these compounds and many uses therefor including application in affinity chromatography enzyme reactors and for preparing dense and porous fibers, fabrics and particles.
