RADIATION CURABLE OLIGOMERS

摘要

Modified acrylated epoxy oligomers include a group of formula (I), where R is a trialkylsilyl group or a phosphorus containing group of formula (II), where R1 and R2 are each alkyl, alkoxy, aryl, aryloxy, aralkyl or aralkoxy groups are radiation curable materials. Such modified oligomers have viscosities which make them suitable for application to substrates, particularly sheet substrates, without substantial dilution with low viscosity monomers; have good compatibility with conventional radiation curable oligomers and are curable on exposure to electron beam radiation to give cured coatings having interesting properties.
