ABSTRACT:
A polystyrene polymer crosslinked by 1.5% to 8% with divinylbenzene based on the total weight of the polymer and having a minimum weight average molecular weight of 10000 wherein 50 to 100% of the aromatic groups of the polystyrene are substituted by at least one --(R.sup.1).sub.n --NHR.sup.2 group wherein R.sup.1 represents a straight or branched chain alkylene or cycloalkylene group of 1 to 6 carbon atoms and n is 0 or 1 and NHR.sup.2 represents a guanidino group of formula --NH--C(.dbd.NH)NH.sub.2 or a biguanidino group of formula --NH--C(.dbd.NH)--NH--C(.dbd.NH)--NH.sub.2 for use in therapy.
