ABSTRACT:
A process is disclosed for the production of bio-compatible polyurethane, proceeding from cyclo aliphatic diisocyanate and macrodiol, which are reacted into a pre-adduct that is then chain lengthened with a mixture of the lower-molecular diol and a macrodiol. The so-obtained polyurethane displays high resistance in human and animal bodies and is suitable for the manufacture of catheters, blood pumps, heart valves, as well as bio-compatible lacquers and coatings.
