Abstract: A biocompatible monomer composition includes: (A) at least one monomer, which forms a medically acceptable polymer; (B) at least one plasticizing agent present in the composition in an amount of from 0.5 wt.% to 15 wt.% of the composition; and (C) at least one acidic stabilizing agent having a pKa ionization constant of from about 1 to about 7. The composition can be applied to a variety of materials and is particularly suitable as in vivo tissue adhesive. A method of joining together in vivo two surfaces, e.g., body tissues, includes (a) holding damaged tissue edges together to form abutted tissue surfaces; (b) applying to the abutted tissue surfaces an excessive amount of a composition containing 1) at least one monomer, which forms a medically acceptable biodegradable polymer, 2) at least one plasticizing agent; and 3) at least one acidic stabilizing agent; and (c) maintaining the surfaces in contact until the composition polymerizes to form a thick film of polymerized composition bridging the abutted tissue surfaces.
