Use of a fluoropolymer as a contrast agent for imaging by magnetic resonance imaging (MRI) 19F solid state scaffold comprising said polymer and use thereof

摘要

Use of a fluorinated polymer having a glass transition temperature (Tg) below 40 ° C, preferably below 20 ° C, more preferably below 0 ° C, even more preferably below -40C as forming component imaging or contrast agent imaging magnetic resonance imaging (MRI) 19F of a solid object, the solid object that mark imaging or contrast agent, characterized in comprising that the solid object further comprises at least one non-fluorinated polymer wherein the fluoropolymer and at least one fluoropolymer not are joined together by covalent or non-covalent, wherein the at least one non-fluorinated polymer is noncovalently bound to the at least one fluoropolymer by hydrogen bond and wherein the at least one fluorinated polymer not bonded via hydrogen bonding is obtained from at least one monomer selected from the group consisting of urethane, urea, bisurea, ureidopyrimidone and combinations thereof.
