摘要

Copolu00ecmeros, process for the preparation of copolu00ecmeros, use of copolu00ecmeros, process for the treatment of superfu00eccies, superfu00eccie of polymeric or superfu00eccie metal article, and aqueous formulation, the invention relates to copolymers containing polymerized with the same as comonu00f3me ROS (a) ethylene, (b) one or more compounds of the general formula 1.(c) optionally one or more alquenilfosfu00f3nicos diesters, (d) if appropriate one or more other comonu00f3meros radically free copolimerizu00e1veis variables defined as follow: R ^ 1 ^ is selected among hydrogen and C ~ 1 ~ C ~ 10 ~ - alkyl branched or not branched, R ^ 2 ^ is selected. Between hydrogen and C ~ 1 ~ C ~ 10 ~ - alkyl branched or not branched, R ^ 3 ^ is selected among hydrogen,Fenila, benzila and C ~ 1 ~ C ~ 10 ~ - alkyl or branched or not branched hydroxy - C ~ 2 ~ - C ~ 10 ~ - alkyl branched or not branched, as a free acid or partly or completely neutralized with alkaline metal, alkaline metal - earthy or organic amine.
