Abstract
The invention relates to activated support materials which comprise epoxy-substituted poly(meth)acrylamides, characterized in that: PA1 a) the base support contains aliphatic hydroxyl groups, PA1 b) the covalently bonded polymers are bonded to the support via a terminal monomer unit, PA1 c) the polymers contain monomer units of the formula I, PA1 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, PA2 R.sup.4 is H or alkyl having 1-5 carbon atoms PA2 and PA2 n is an integer between 1 and 5 and to the use thereof.
