Abstract:
1. An ambiently degradable aqueous gel formulation comprising: (a) water; and (b) a water-absorbent, ambiently degradable co-polymer having wherein functional groups R and R 1 in said base structures are alkyl groups independently selected at each instance from the family consisting of methyl (CH 3 ), ethyl (C 2 H 5 ), and propyl (C 3 H 7 ) groups, the value of n in said first and second repeating base structures being selected such that the molecular weight of said co-polymer is than 50 000 Daltons(Da); wherein each of the n building blocks of said first repeating base structure is crosslinked to a corresponding second building block of said second repeating base structure, via an ambiently biodegradable crosslinking structure, by means of at least two of: said carboxyl ion and said first and second carbonyl moieties, wherein said water is absorbed within said degradable copolymer, and wherein the gel formulation has a viscosity in a range of 500 cps to 50,000 cps.
