Abstract: The invention relates to a process for the production of cyclocopolymers, characterised in that compounds of the general formula 1

In which n is 1 - 4; R.sup.3 is H, CH.sub.3 or --CH.sub.2 --CH; Y is OH or NH.sub.2 ; and R.sup.4 and R.sup.5 may be identical or different and mean hydrogen or (C.sub.1 -C.sub.4)-alkyl, Preferably in equimolar amounts, and possibly with the use of further unsaturated compounds which are copolymerisable with compounds of the formula 1 and to copolymers obtainable by the process of the invention.

Where R means hydrogen, an aliphatic or aromatic radical, are copolymerised with unsaturated compounds of the general formula 2

In which R.sup.1 and R.sup.2 may be identical or different and mean H, CH.sub.3, C1 or Br; and X means

Abstract: (Meth)acrylamidomethylene carbamic acid (meth)allyl esters and at least one other copolymerizable monomer are copolymerized by, solution, emulsion or suspension polymerization at temperatures of below about 60*C in the presence of radical-forming agents. Dispersions of the self-crosslinkable copolymers are particularly suitable for impregnating, consolidating and coating non-woven fabric, for coating metal substrates and as dressing for leather.
