Abstract
There is provided a polymeric bacteriocidal composition comprising a thermoplastic, partially cross-linked polyurethane having --NH--(C.dbd.O)--O-- urethane linkages and/or urea linkages --NH--(C.dbd.O)--NH-- and iodine complexed with a sufficient number of these linkages to provide bacteriocidal properties to said composition. The polyurethane has an average molecular weight between 35,000 and 50,000, an ultimate elongation of 200 to 800% and a Shore A scale hardness of 60 to 95. The composition is shaped into a conventional medical appliance form, e.g. a catheter.
