Abstract: Process for the manufacture of surface-sized papers by impregnating a paper with a solution containing a water-soluble salt of a random polymer based on .alpha.-olefins and ethylenically unsaturated acids and a compound of the formula: ##EQU1## wherein R is alkyl, aryl or a radical of the formula: ##EQU2## and R.sup.1 and R.sup.2 each independently denotes H, R or a radical of the formula:R -- O-- CH.sub.2 --and drying the impregnated paper. Very well sized papers are obtained which show alkali resistance and filler compatibility.

Abstract: Soluble adduct polymers were allowed to react with nitrogenous compounds such as urea, trimethylolmelamine, and ammonia to (a) prepare flame resistant polymers and (b) prepare flame-, glow-, wrinkle-, and shrink-resistant woven and knit textiles which contain 25% or more cellulosic fibers.

Abstract: A novel method of preparing a waterless lithographic master and a method of printing therefrom are provided. To prepare the printing master, a suitable ink accepting substrate such as aluminum, paper or plastic, is coated with a silicone gum curing catalyst, preferably suspended in a hydrophilic binder. A barrier fusable particulate hydrophobic image pattern is then deposited on said coated substrate and fused to mask said curing catalyst in the image areas. The substrate is then coated with an uncured silicone gum, preferably as an aqueous emulsion so that the gum does not adhere to the hydrophobic image pattern. The silicone gum is then cured in the nonimage areas to selectively provide ink receptive image areas and ink releasing nonimage areas. The method of printing comprises the additional steps of applying ink to the imaged master and contacting the inked master with an image receiving surface to thereby transfer the inked image.

Abstract: Modified synthetic fibers having durable antistatic property, hygroscopic property and anti-fouling property at the same time are obtained by adhering onto the surface of synthetic fibers, a small amount of reaction product of a s-triazine derivative or a piperazine derivative expressed by a certain general formula (I)-a or (I)-b, with a derivative of polyoxyethylene expressed by a general formula (II) (pretreatment), and further adhering onto the resulting fibers, a small amount of an aromatic sulfonic acid expressed by a general formula (III) (post-treatment).

Abstract: A process of making a decorative surface covering by preparing a granular resinous dryblend containing a vinyl resin and a plasticizer for the vinyl resin, depositing a layer of the dryblend on a backing, heating the granules to form a porous, cohesive layer therefrom, cooling the layer, and printing a decorative design on the porous layer with a first printing composition containing a polymerization inhibitor which will penetrate into the porous composition. A second printing composition containing both a polymerizable monomer, compatible with the plasticized vinyl resin, and having at least two olefinically unsaturated sites, and, a polymerization catalyst for the monomer is then applied over the entire surface of the printed layer, and heat and/or heat and pressure is applied to fuse the resinous granules and polymerize the monomer throughout those areas not printed with the polymerization inhibitor composition.

Abstract: Hydroxymethylphosphine-ammonia and similar polymers, solubilized by hydroxymethylphosphonium salts and formaldehyde, were allowed to react with nitrogenous compounds such as urea, trimethylolmelamine and ammonia to (a) prepare flame-resistant polymers and (b) prepare flame-, glow-, wrinkle and shrink-resistant woven and knit textiles which contain 25% or more cellulosic fibers.

Abstract: New carbamide-formaldehyde condensation products which possess at least one hydrophilic and at least one hydrophobic radical, characterised in that at least one hydrophobic radical is bonded via a ##EQU1## bridge, wherein A denotes hydrogen or alkyl with 1 to 4 carbon atoms, and at least one hydrophilic radical is bonded via a N-methylol-ether bridge, to a cyclic or acyclic urea radical, these products are particularly useful as reactive surface-active agents.

Abstract: After vacuum pressure impregnating an insulated coil with liquid polyester resin the outer surface of the combination is treated to cause a quick low temperature gellation of an outer shell of the resin to thereby encapsulate the remaining liquid portion. A subsequent high temperature cure is imposed for a relatively long period of time to solidify the liquid inner portion and to fully cure the resin throughout the insulation.

Abstract: A process is disclosed for manufacturing flat shaped articles made of individual fibers such as paper, woven fabric, knitted fabric and non-woven fabric impregnated with an aqueous dispersion of a polymeric binder including a sensitizing agent for causing the dispersion to coagulate at a temperature substantially below 100.degree.C. The binder coagulates at a temperature substantially below 100.degree.C. and the method includes impinging live steam on the major surfaces of the article to suddenly coagulate the binder, thereby fixing its position within the fabric and preventing its migration to the fabric's surfaces. One or more adjustable position steam nozzles are used for this purpose.

Abstract: Wood can be rendered fire resistant by impregnating the wood with a solution of a monomer, such as a phenol, and a fire-inhibiting salt, drying the wood and thereafter treating the wood with a solution of a second monomer, such as formaldehyde, polymerizable with the first monomer. Heating to dryness causes polymerization of the monomers. The fire resistant properties of wood treated this way are not affected by exposure to moisture. Prior to the first impregnation, after the first impregnation and after treatment with the second monomer the wood being treated is dried to a moisture content below about 4%.
