Abstract
The invention relates to new, pharmaceutically active copolymers with heparin-like activity, pharmaceutically acceptable salts thereof and a process for their preparation. The new copolymers comprise the units of the formula I ##STR1## wherein X stands for hydrogen or methyl and Y is hydrogen, units of the formula III ##STR2## optionally units of the formula II ##STR3## wherein Z' is hydrogen, and chain terminating units, formed from the units of the formulae I, III and optionally II under the conditions of copolymerization, in a statistical arrangement, and the pharmaceutically acceptable salts thereof, which contain, in addition to the above chain-members, units of the formulae IV and/or V ##STR4## wherein A is a cation/ satisfactorily replace the organogenic heparin, or give a synergistic combination with that,
