| Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, or kaolin clay) to remove impurities such as sand. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. | ||||||

| 89 | RADIOOPAQUE, IODINE FUNCTIONALIZED PHENYLALANINE-BASED POLY(ESTER UREA)S | US15330815 | 2015-05-07 | US20170081476A1 | 2017-03-23 | Matthew L. BECKER; Shan LI |
| In one or more embodiments, the present invention provides iodine-functionalized phenylalanine-based poly(ester urea)s (PEUs) (and related methods for their synthesis and use) that are metal free, degradable, radiopaque and suitable for use in surgical implants and other medical devices used within a patient. In one or more embodiment of the present invention 4-Iodo-L-phenylalanine and L-phenylalanine are separately reacted with 1,6-hexanediol to produce two monomers, bis-4-I-L-phenylalanine-1,6-hexanediol-diester (1-IPHE-6 monomer) and bis-L-phenylalanine-1,6-hexanediol-diester (1-PHE-6 monomer). It has been found that by varying the feed ratio of the 1-IPHE-6 and 1-PHE-6 monomers, the copolymer composition may be modulated to predictably create phenylalanine-based PEUs having a wide variation in thermal, mechanical and radiopacity properties. As most medical device procedures require placement verification via fluoroscopic imaging, materials that possess inherent X-ray contrast are valuable for a number of applications. | ||||||
