ABSTRACT:
A process is disclosed for producing a medical prosthesis by forming the prosthesis from an uncrosslinked polyurethane and then at least partially crosslinking the polyurethane with a vaporizable halo alkylisocyanate. The haloalkylisocyanate (e.g. chloromethylisocyanate) is reacted with the uncrosslinked polyurethane at a temperature which will not degrade or soften the polyurethane, (in its uncrosslinked form) in order to crosslink the polyurethane.
