Abstract
Absorbable and non-absorbable cyanoacrylate tissue adhesive/sealant formulations include at least one multipurpose carboxylic, acid-bearing C-succinylated polymeric rheology modifier capable of increasing the viscosity of the liquid formulation, while controlling the anionic polymerization of the cyanoacrylate monomers and increasing the compliance of the cured solid adhesive.
