Abstract

The present invention relates generally to synthetic polymer compositions that form interpenetrating polymer networks. In a preferred embodiment, the compositions comprise two multifunctionally activated synthetic polymers, along with a tensile strength enhancer. Such compositions form matrices that exhibit superior cohesive strength and in many instances can serve as adequate replacements for surgical means of attaching tissues, such as sutures, sponges and medical staples.
