ABSTRACT:
The invention relates to polymeric materials containing variable amounts of aldehyde groups and comprising the chain units ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are H, C.sub.1 - C.sub.5 alkyl, aryl, furyl, halogen, nitrile group or hydroxyl and R.sup.4 is C.sub.1 - C.sub.20 alkylene, arylene, --COO(CH.sub.2).sub.n --, --O--(CH.sub.2).sub.n --, --COO(CH.sub.2).sub.n CH(OH)CH.sub.2 OCO(CH.sub.2).sub.m -- or --(CH.sub.2).sub.n OCOR.sup.5 COO(CH.sub.2).sub.m -- (n and m are integers 0 - 20 and R.sup.5 is the single bond, C.sub.1 - C.sub.20 alkylene or hydroxyalkylene or arylene). The material may be in the form of globules with a measurable specific surface area and is suitable for bonding of biologically active compounds containing primary amino groups or other amines to produce polymeric chelating agents. The invention further relates to the method for preparation the above materials which consists in treatment of the polymeric materials comprising units of the general formula ##STR2## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 have the aforesaid meaning and R.sup.6 is H, C.sub.1 - C.sub.20 alkyl or aryl, with the aqueous solution of periodic acid at 0.degree. - 200.degree. C and the pressure 1 Pa to 20 MPa.
