Abstract:
1. A solid object comprising an imaging label or contrast agent including a (per)fluorinated polyether polymer having a glass transition temperature (Tg) below 40° C., which is visible by 19 F magnetic resonance imaging (MRI) of the solid object, wherein the solid object further comprises at least one non-fluorinated polymer wherein the (per)fluorinated polyether polymer and the at least one non-fluorinated polymer are bonded together by covalent or non-covalent bonding, wherein the at least non-fluorinated polymer is obtained from at least one monomer selected from the group consisting of urethane, urea, bisurea, ureidopyrimidone and combinations thereof wherein the amount of fluorine ( 19 F) in the (per)fluorinated polyether polymer is at least 5 wt %, based on the total mass of the polymer.
