Crosslinked copolymers in which the crosslinking via bridge members of the formula where R 'and R 2 independently of one another are hydrogen or alkyl having 1 to 4 carbon atoms and m is a number from 0 to 6, takes place.n n n The products are manufactured by copolymerizing known monomers with vinylphosphonic acid (ester) anhydrides.n n n The novel polymers according to the invention are suitable for the production of acid-soluble coatings and encapsulation materials, as dyeing aids, as cementing aids and as absorbents for aqueous liquids. |
