Abstract
A composition which is cured upon exposure to ultraviolet light in the absence of solvent is disclosed. The liquid composition is prepared by combining a liquid maleate polyester and at least one of a vinyl compound and an allyl functional compound. A photoinitiator is then added to the polymerizable liquid composition. A substrate is impregnated with the polymerizable liquid composition and exposed to actinic energy of a sufficient dosage for a sufficient amount of time to polymerize the composition to a sufficient degree to impart useful properties to the substrate. The composition can be used as a binder for fiberglass insulation, in the manufacture of transparent or semi-transparent paper and to manufacture paper for use in photocopy machines.
