| titleOfInvention | Water insoluble cross-linked polycarbonic acid compositions |
| abstract | There is provided water insoluble cross-linked polyhydroxy polycarboxylic acid having at least two strands each having a strand skeleton of forumula (III) wherein one carbonyl group of at least one maleoyl moiety thereof in each strand is covalently linked to a -HN.ยข(H)p(CH)z.(OH)m!.NH- moiety to provide the presence therein of at least one cross linking moiety of formula (V), wherein R is hydrogen or lower alkylene or lower alkoxy of 1-4 carbon atoms, or phenyl, z is an integer of 1 - 4, p is 0 or an integer up to z - 1, m is 1 or an integer up to z, wherein the ratio of cross-links to poly (alkylene carbonic acid) strands is between about 1 and about 200 to 2. There is disclosed a method of making such polyhydroxy polycarboxylic acid as well as methods of utilizing same to remove proteins from aqueous media containing same to provide a matrix. Methods are disclosed for recovering proteins from said matrix without denaturing them and methods for recovering the polyhydroxy polycarboxylic acid from said matrix. |
