ABSTRACT:
Novel amides, preferably having a molecular weight in the range 1000 to 10,000, are prepared by acylating, partially or fully, amino groups in poly(ethylene imine) or poly(propylene imine) whereby amino-hydrogen atoms are replaced by groups R.sup.3 CH.dbd.CR.sup.2 CO--, where R.sup.3 denotes an aliphatic, cycloaliphatic, araliphatic, or heterocyclic group containing ethylenic unsaturation in conjugation with the indicated double bond and R.sup.2 denotes a hydrogen, chlorine, or bromine atom, a cyano group, or an alkyl group. Particularly preferred are such amides where R.sup.3 CH.dbd.CR.sup.2 CO-- denotes a sorbyl group and containing additional intramolecular linkages introduced by a difunctional reagent capable of reacting with aliphatic amino groups, such as a diepoxide or a di-isocyanate.
The amides may be polymerized by means of actinic radiation and are useful in the preparation of printing plates and printed circuits.
