    摘要: 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 first and 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-[(C 3 H 6 O) n -(C 2 H 4 O) 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.
