Iodinated and/or brominated derivatives of aromatic dihydroxy monomers are prepared and polymerized to form radio-opaque polymers. The monomers may also be copolymerized with other dihydroxy monomers. The iodinated and brominatad aromatic dihydroxy monomers can be employed as radio-opacifying, biocompatible non-toxic additives for other polymeric biomaterials. Radio-opaque medical implants and drug delivery devices for implantation prepared from the polymers of the present invention are also disclosed.

Des dérivés iodés et bromés de monomères dihydroxyaromatiques sont préparés et polymérisés pour obtenir des polymères radio-opaques. Les monomères peuvent aussi être copolymérisés avec d'autres monomères dihydroxylés. Les monomères dihydroxyaromatiques iodés et bromés peuvent être utilisés comme additifs radio-opacifiants, biocompatibles et non toxiques pour d'autres biomatériaux polymères. On divulgue également des implants médicaux radio-opaques et des dispositifs d'administration de drogues à implanter préparés au moyen des polymères de la présente invention.
