Abstract
A polymerizable adhesive composition that forms an interpenetrating network when the components are polymerized. A sirup is made with a styrenic prepolymer, (meth)acrylate monomer and multifunctional (meth)acrylate crosslinking agent. The adhesive composition afforded by this sirup is polymerized in place using a conventional free radical initiators and activators. The adhesive is found especially useful as a joint adhesive for solid surface materials.
