In one or more embodiments, the present invention relates to a substantially homogeneous miscible liquid adhesive composition comprising a relatively high number average molecular weight (Mn=6,000-10,000 g/mole) cyanoacrylate tri-telechelic star polymer having polyisobutylene chains terminated with cyanoacrylate groups (High-Ø(PIB-CA)3) 2-octyl cyanoacrylate (Oct-CA) and a relatively low molecular weight (Mn=1,000-4,000 g/mole) cyanoacrylate tri-telechelic star polymer having polyisobutylene chains terminated with cyanoacrylate groups (Low-Ø(PIB-CA)3). The Low-Ø(PIB-CA)3 compatibilizes the High-Ø(PIB-CA)3 and Oct-CA removing the need for a solvent. When the substantially homogeneous miscible liquid adhesive compositions of various embodiments are reacted with a nucleophile, such as water or an initiator, they form a polymer co-network suitable for any of a number of biomedical applications, from wound closure and healing of skin tissue, to sealant for surgical cuts.
