Abstract
A polymerizable composition, suitable for use as an adhesive, sealant or coating, comprising a urethane-acrylate-capped prepolymer based on a graft polyol derived from the reaction between the polyol and a vinyl monomer or polymer. In a preferred embodiment, the graft polyol is present as the disperse phase of a polymer/polyol dispersion. The composition provides improved general properties, particularly cure-through-gap and impact properties. The composition typically has a relatively low viscosity, making it especially useful for 'retaining' purposes. A process for preparing the composition and a process for using it are also disclosed.
