New oligomeric polyurethanes have been prepared from polyether diols, chain extender and 4,4': dicyclohexylmethane diisocyanate or 4,4'-diphenylmethane diisocyanate, which are terminated with a mixture of 2-hydroxyethyl methacrylate (2-HEMA) and non-functional terminators such as n-propanol or technical hydroabietyl alcohol. The oligomers may be cured by electron beam or u.v. radiation to give pressure-sensitive adhesives.
