Abstract
The invention relates to activated support materials which comprise epoxy-substituted poly(meth)acrylamides, characterized in that: a) the base support contains aliphatic hydroxyl groups, b) the covalently bonded polymers are bonded to the support via a terminal monomer unit, c) the polymers contain monomer units of the formula I, d) the monomer units are linearly linked, ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 independently of one another are H or CH.sub.3, R.sup.4 is H or alkyl having 1-5 carbon atoms and n is an integer between 1 and 5 and to the use thereof.

An activated support material comprising a base support having polymer covalently bonded to a surface thereof, wherein
- a) the base support contains aliphatic hydroxyl groups
- b) the polymer is covalently bonded to the support via a terminal monomer unit,
- c) the polymer contains monomer units of the formula I having an epoxide group, ##STR4## in which R.sup.1, R.sup.2 and R.sup.3 independently of one another are H or CH.sub.3,
- R.sup.4 is H or alkyl having 1-5 carbon atoms
- and
- n is an integer between 1 and 5, and
- d) the monomer units are linearly linked.
A process for the preparation of an activated support material, comprising a base support having polymer covalently bonded by graft polymerization to a surface thereof, comprising:
- a) acryloylating a chlorohydrin-containing alkyl-amine of the formula II ##STR5## in which R.sup.4 is H or alkyl having 1-5 carbon atoms
- and
- n is an integer between 1 and 5,to provide monomers;
- b) graft polymerizing the monomers from a) onto a hydroxyl-containing base support particle in the presence of cerium(V) ions;
- and
- c) reacting the chlorohydrin radicals to convert them to epoxide groups.
