    Abstract: A method of preparing a laminate having increased peel strength and solvent resistance which involves (A) applying an adhesive composition to a surface of a first sheet; (B) exposing the adhesive composition on the surface of the first sheet to incoherent, pulsed ultraviolet radiation from a dielectric barrier discharge excimer lamp; (C) bringing a surface of a second sheet in contact with the adhesive composition-bearing surface of the first article; and (D) allowing the adhesive composition to cure. The incoherent, pulsed ultraviolet radiation has a single narrow wavelength band within the range of from about 260 to about 360 nanometers. The adhesive composition includes from about 94 to about 60 percent by weight of a cycloaliphatic diepoxide, from about 1 to about 10 percent by weight of a cationic photoinitiator, and from about 5 to about 30 percent by weight of a vinyl chloride-vinyl acetate-vinyl alcohol terpolymer, all based on the weight of adhesive composition. The sheets desirably are films and nonwoven webs composed of cellulosic fibers, polyolefin fibers, or a mixture of cellulosic fibers and polyolefin fibers. The method is particularly well suited for the preparation of such laminates as industrial wipers, workwear, medical fabrics, and the like.

    Abstract: A composite material comprising an elastomer and nanocellulose. The nanocellulose may compirse a nanocellulose material derived from plants having C4 leaf anatomy, or a nanocellulose material derived from a plant material having a lesser amount of lignin than hemicellulose, or a nanocellulose having a hemicellulose content of from 25% to 55% by weight of the nanocellulose material, or a nanocellulose comprising nanofibrils having a diameter of up to 5nm, or a nanocellulose comprising nanocellulose material of plant origin comprising nanocellulose particles or fibres having an aspect ratio of at least 250, or the composite material having a stiffness of not greater than 2.5 times the stiffness of the elastomer without the nanocellulose material being present, or the nanocellulose particles or fibres being derived from a plant material having a hemicellulose content of 30% or higher (w/w). The nanocellulose may be derived from arid Spinifex.
