Methods for making biomaterials for use as a tissue sealant, kits containing precursors for forming the biomaterials, and the resulting biomaterials are described herein. The biomaterials are formed from a composition comprising at least a firstand a second precursor molecule, wherein: i)the first precursor molecule is a poly(ethylene glycol) based polymer having x nucleophilic groups selected from the group consisting of thiol or amino groups, wherein x is equal to 2 or greater than 2, preferably 3, 4, 5, 6, 7 or 8; ii)the second precursor molecule is of the general formula: A-[(C3H6O) n-(C2H4O) m-B] i wherein m and n are integers from 1 to 200 i is greater than 2, preferably 3, 4, 5, 6, 7 or 8 A is a branch point B is a conjugated unsaturated group. |
