Abstract: Method of partially converting wood into plastic material by impregnating the wood with a phenol and substances which form a reaction product which forms a prepolymer with the lignin in the wood, heating said impregnated wood to form said reaction product and pre-polymer, and thus applying further heat and pressure to said impregnated wood to form a copolymer between said pre-polymer and the lignin in said wood.

Abstract: Aqueous phenolic resole dispersions are disclosed. The dispersions are produced in the presence of gum ghatti and a thickening agent. The dispersions of the invention contain phenolic resole particles that can be very small and uniform in size, thereby enhancing the utility of said dispersions in such end-use applications as coatings and adhesives.

Abstract: Filled composite plastics are prepared, which consist entirely of a rigid filler which has been graft polymerized with a thermoplastic polymer. The conventional thermoplastic matrix has been eliminated. When the rigid filler is a polysaccharide, such as starch, a product with improved biodegradability is produced. Also, valuable petroleum reserves are conserved, since the polysaccharide portion serves as an extender for the petroleum-based polymer.

Abstract: An economic process is provided for effectively drying wet, highly swollen, polymer-modified, cellulosic fibres to provide fibres having enhanced properties of both water and physiological liquid retention. The essential steps of the drying process are as follows: First, the hydrolyzed fibres are thoroughly washed with water, thus rendering them to a substantially maximum swollen state. The fibres are then acidified to a low, critical pH whereby the water previously retained by the alkaline fibre is released and filtered off, thus rendering them to a substantially minimum swollen state. The product may be subjected to an optional non-shearing stirring step while in a low consistency dispersion prior to the acidification step. Further treatment with an alkali non-swelling solvent mixture renders the fibres substantially water-free in their alkaline salt form.

Abstract: Alkyd resin lacquers which contain cellulose nitric acid esters can be prevented from "lifting" and yellowing by the addition of bis-[hydroxyphenyl]-alkanes which are substituted in the nucleus.
