A process is described that results in the production of a hydrophilic air-drying polymer system suitable for increasing the inter-fiber bonding in a fibrous substrate material. The process comprises passing air through a monomer maintained at a temperature below about 30°C., said monomer having at least two activated unsaturations, until a desired viscosity increase has been achieved.

Polymer compositions are described that confer an enhanced balance of wet and dry strength properties to a cellulosic substrate while leaving the substrate soft and porous. The compositions comprise a hydrophilic air-curing polymer and a polyol with a carbon to oxygen ratio of less than 3:1, typified by glycerol.
A process for coating a substrate with a film comprising an α,β-ethylenically unsaturated compound, a β,γ-unsaturated ether activator compound, an effective amount of a free radical polymerization initiator, and, optionally, a catalytic amount of metal drier. The components are applied to the substrate and the coated substrate is then placed in an atmosphere substantially free of oxygen until the coating has cured to a substantially tack-free condition.
