Abstract: A high pressure laminate is made of several layers of paper, including from bottom to top core sheets, a decor sheet and an overlay sheet. The core sheets are either composed of cellulose fibers or composed of 30 to 90 weight percent cellulose acetate fibers and 70 to 10 weight percent cellulose fibers. The core sheets are respectively coated with either a lamination polymer or a plasticizer. The decor sheet is composed of a mixture and a conventional amount of paper making dye. The mixture comprises 30 to 90 weight percent cellulose acetate fibers, 10 to 70 weight percent celluose fibers and 0 to 20 weight percent fillers. The decor sheet is coated with a plasticizer. The overly sheet is composed of cellulose fibers and is coated with a lamination polymer. Upon application of heat and pressure to the several layers a laminate is formed having thermoplastic, properties, improved postformability and a significant reduction in the release of volatile organics during formation.

Abstract: Disclosed is a radiation cross-linkable water-dispersible adhesive composition that is useful in forming paper and plastic articles and other products that can be recycled through a process which includes washing or repulping in aqueous media. The cross-linkable water-dispersible adhesive composition is preferably used as a hot melt adhesive. The cross-linkable water-dispersible adhesive composition is a low molecular weight, branched copolyester containing a sulfomonomer and unsaturated moieties. The radiation cross-linked adhesive composition has more cohesive strength and viscosity that its corresponding uncross-linked adhesive, yet is still water-dispersible during product recycling.

Abstract: A new process is described for recycling polyesters. In accordance with the described process, postconsumer or scrap polyester is reacted with glycol to produce a monomer or low molecular weight oligomer by depolymerization of the polyester. The monomer or oligomer, as the case may be, is then purified using one or more of a number of steps including filtration, crystallization, and optionally adsorbent treatment or evaporation. The monomer or oligomer thus produced is particularly suitable as a raw material for acid or ester based polyester production of packaging grade polyester material. Because the process includes purification steps, specifications for the previously used polyester material need not be strict.

Abstract: The present invention relates to a modified cellulose ester containing unsaturated pendant groups which can be prepared by reacting a cellulose ester containing residual hydroxyl groups with, for example, maleic anhydride in acetic acid solvent with sodium acetate catalyst. The modified cellulose ester is not homopolymerizable but will copolymerize in the presence of vinyl cross-linking agents and a photoinitiator upon exposure to ultraviolet radiation. The modified cellulose ester is useful as a protective and/or decorative coating for wood, metal, plastics, paper, board, and other substrates, as well as an additive to printing inks, and as a nail polish. In addition, because of the propensity for the pendant carboxyl groups to form hydrophilic salts with amines, the modified cellulose esters can be formulated to be water-dispersible.

Abstract: This invention provides a method for rendering a water-based coating (i.e., one which contains essentially no organic solvent) fluorescent. Also provided is a method for measuring the extent of coverage and thickness of a water-based coating by incorporating therein a minor amount of an emulsion of an insoluble compound which absorbs ultraviolet light and fluoresces strongly in the visible region of the spectrum, so that the intensity of the fluorescence serves as an indication of the degree of coverage and thickness of the film. Also provided is a method for enhancing the apparent brightness of a film pigmented with light colored pigments. In the case where white pigments such as titanium dioxide are used, the effect is to increase the apparent whiteness of the film.
