Title:
RADIOPAQUE POLYMERS
Document Type and Number:
Japanese Patent JP2023078148
Kind Code:
A
Abstract:
To provide iodinated polymers that are sufficiently radiopaque to be visible on X-ray.SOLUTION: A hydrophilic polymer comprises a pendant group of formula (I), where W is independently selected from -OH, -COOH, -SO3H, -OPO3H2, -O-(C1-4 alkyl), -O-(C1-4 alkyl) OH, -O-(C1-4 alkyl) R2, -O-(C2H5O)qR1-(C=O)-O-C1-4 alkyl and -O-(C=O) C1-4 alkyl, 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; and G is a coupling group through which the group of the formula (I) is coupled to the polymer.SELECTED DRAWING: Figure 1
