Abstract:
A biodegradable, photopolymerizable, and at least substantially water soluble macromer comprising:components P, B, and L, wherein P comprises an organic group capable of being crosslinked by photopolymerization, L is a linking group, comprising at least one repeating unit, and L exhibits water solubility or biodegradability, and B is a backbone group, comprising at least one repeating unit, and B exhibits water solubility or biodegradability;wherein each P is separated by at least one biodegradable group from any other P;wherein at least one of B and L is biodegradable;wherein at least one of the repeating units of B and L are different;wherein the macromer as a whole is substantially water soluble;wherein there are at least two P groups per molecule; andwherein a plurality of P groups are linked to B groups via L groups.
