ABSTRACT:
The invention provides amidoxime derivatives of the general formula ##STR1## wherein R.sub.1 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. R.sub.2 is a mono or bicyclic heterocyclic radical containing at least two nitrogen atoms which radical is also optionally substituted. R.sub.3 and R.sub.4 are independently H, or an alkyl of 1 to 4 carbon atoms or one, but not both, is ##STR2## and the other, H, wherein R.sub.5 or R.sub.6 are alkyls of 2 to 5 carbon atoms optionally substituted by R.sub.1, or a phenyl optionally substituted by R.sub.1 or R.sub.5 or R.sub.6 is combined with R.sub.1 to jointly form cyclic imidoximes or imidedioximes. The invention 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.
