Abstract
Abstract A polymerizable composition, suitable for use as an adhesive, sealant or coating, comprising a urethane-acrylate-capped prepolymer based on a polymeric or copolymeric alkylene ether polyol. The composition provides improved properties, particularly cure-through-gap, impact and cryogenic strength properties. A process for preparing the composition and a process for using it are also disclosed.
