ABSTRACT:
New copolymers obtained by interpolymerization of alkylacrylate (25 to 85 %), methacrylic acid (15 to 75 %), trialkyloxyvinylsilane (0.1 to 2 %) and monomer acting as reticulating agent, for example: divinylbenzene, alkyl compound, etc. (0.01 to 0.5 %). The above indicated percentages are in weight of the total monomer mixture.
These copolymers are used, in form of emulsions, as thickening agents for aqueous systems of polymers, for example of acrylic copolymers.
