Abstract
Official abstract text for this publication.
An embodiment includes a polymer composition comprising a thermoplastic polymer that: (a) is bonded to iodine, (b) includes a vinyl group, and (c) includes urethane linkages. Other embodiments are described herein.
First claim
Opening claim text (preview).
What is claimed is: 1 . A polymer composition comprising: a thermoplastic polymer that: (a) is bonded to iodine, (b) includes a vinyl group, and (c) includes urethane linkages; wherein the iodine is included in a triiodobenzene monomer; wherein the thermoplastic polymer includes a backbone that comprises the triiodobenzene monomer; wherein the triiodobenzene monomer includes at least one of (a) 5-amino-2,4,6-triiodoisophthalic acid (ATIPA), (b) diatrizoic acid, (c) triiodophenol, or (d) iothalmic acid. 2 . The polymer composition of claim 1 wherein the thermoplastic polymer is radiopaque. 3 . The polymer composition of claim 1 wherein the triiodobenzene monomer includes ATIPA. 4 . The polymer composition of claim 1 wherein the triiodobenzene monomer includes a functional group, the functional group comprising one of the vinyl group and an additional vinyl group. 5 . The polymer composition of claim 1 wherein the triiodobenzene monomer is linked to the backbone with at least one of an amide linkage, a urethane linkage, or a urea linkage. 6 . A polymer composition comprising: a thermoplastic polymer that: (a) is bonded to iodine, (b) includes a vinyl group, and (c) includes urethane linkages; wherein the iodine is included in a triiodobenzene monomer; wherein the thermoplastic polymer includes a backbone having a repeating unit, the repeating unit including the iodine and a functional group; wherein the functional group comprises an additional vinyl group. 7 . The polymer composition of claim 6 wherein the triiodobenzene monomer includes at least one of (a) 5-amino-2,4,6-triiodoisophthalic acid (ATIPA), (b) diatrizoic acid, (c) triiodophenol, or (d) iothalmic acid. 8 . The polymer composition of claim 7 wherein the triiodobenzene monomer includes ATIPA. 9 . The polymer composition of claim 4 wherein the functional group includes the additional vinyl group.
