Radiopaque polymers

A hydrophilic polymer comprising pendent groups of the formula I: Wherein: W is independently selected from &#x2014;OH, &#x2014;COOH, &#x2014;SOH, &#x2014;OPOH, &#x2014;O&#x2014;(Calkyl), &#x2014;O&#x2014;(Calkyl)OH, &#x2014;O&#x2014;(Calkyl)R, &#x2014;O&#x2014;(CHO)R&#x2014;(C&#x2550;O)&#x2014;O&#x2014;Calkyl and &#x2014;O&#x2014;(C&#x2550;O)Calkyl; or a group &#x2014;BZ; wherein &#x2014;OH, COOH, O&#x2014;POH and SOH maybe in the form of a pharmaceutically acceptable salt; wherein: B is a bond, or a straight branched alkanediyl, oxyalkylene, alkylene oxaalkylene, or alkylene (oligooxalkylene) group, optionally containing one or more fluorine substituents; and Z is an ammonium, phosphonium, or sulphonium phosphate or phosphonate ester zwitterionic group; X is either a bond or a linking group having 1 to 8 carbons and optionally 1 to 4 heteroatoms selected from O, N and S; G is a coupling group through which the group of the formula I is coupled to the polymer and is selected from ether, ester, amide, carbonate, carbamate, 1,3 dioxolone, and 1,3 dioxane; Ris H or Calkyl; Ris &#x2014;COOH, &#x2014;SOH, or &#x2014;OPOHq is an integer from 1 to 4; n is an integer from 1 to 4; p is an integer from 1 to 3; and n+p is from 2 to 5; and wherein &#x2014;COOH, &#x2014;OPOHand &#x2014;SOH as well as phenolic &#x2014;OH maybe in the form of a pharmaceutically acceptable salt.
