Claim Text:
1. A gel-forming composition comprising: a first thermoreversible gelling block copolymer that includes a hydrophilic block and a hydrophobic block, the first thermoreversible gelling copolymer including acrylate functionality in at least a portion of the termini of the copolymer; a second thermoreversible gelling block copolymer that differs from the first thermoreversible gelling block copolymer and includes a hydrophilic block and a hydrophobic block, the second thermoreversible gelling copolymer including acrylate functionality on a portion of the termini of the copolymer and further including amine-reactive functionality on a portion of the termini, the hydrophilic block of the second thermoreversible gelling block copolymer being the same or different as the hydrophilic block of the first thermoreversible gelling block copolymer and the hydrophobic block of the second thermo reversible gelling block copolymer being the same or different as the hydrophobic block of the first thermoreversible gelling block copolymer; and a polyfunctional thiol crosslinker; the composition comprising the first thermoreversible gelling block copolymer and the second thermoreversible gelling block copolymer in a blend at a ratio of from about 10:90 to about 90:10 by weight, respectively.
