The present invention describes the preparation of highly-performing “Acrylamide Free” polyelectrolytic polymers by using not toxic monomers and the way such new monomers can be advantageously used in the field of several civil and/or industrial applications.The new polyelectrolytic polymers developed herein can be then used both as replacement of the common acrylamide-based polymers and in the applications wherein the absence of residual toxic polymerization monomers is requested.
