Abstract:
Radiopaque hydrogels, in particular radiopaque hydrogel microspheres comprising a polymer having 1,2-diol or 1,3-diol groups acetalised with radiopaque species.

Claim (Index 36):
A polyvinyl alcohol (PVA) polymer comprising 1,3-diol groups of the PVA acetalised with a radiopaque species, such that the PVA backbone comprises a structure according to the general formula I wherein X is a group of the formula\n ZQ\u2003\u2003II \n wherein: Z is a linking group, or is absent, such that Q is directly bonded to the cyclic acetal; if Z is present, then Z is C 1-6  alkylene, C 2-6  alkenylene, C 2-6  alkynylene, C 1-6  alkoxylene or C 1-6  alkoxyalkylene; Q is a C 5  to C 12  aryl, or heteroaryl; and Q is substituted by one or more iodines.
