    Abstract: Flame-retardant synthetic resin articles and methods of making the same are provided whereby flame-retardant SAP particles are incorporated into synthetic resins, especially curable thermosettable resins. The SAP particles are most preferably hydrated with an aqueous flame-retardant solution. In this regard, the flame-retardant solution may consist essentially of water alone or a water solution containing one or more water soluble inorganic flame retardants. When SAP particles are hydrated with an aqueous inorganic flame retardant solution, the SAP particles may thereafter be dried to remove substantially the water component. In such a manner, the inorganic flame retardant will remain as a dried residue physically entrained within the SAP particles. As such, the SAP particles serve as a physical matrix in which the inorganic flame retardant is homogenously dispersed. The SAP particles may then be blended with a synthetic resin as is or alternatively may be ground into more finely divided particles which contain the dried residue of the aqueous inorganic flame retardant solution and then blended with a suitable synthetic resin.

    Abstract translation: 提供阻燃合成树脂制品及其制备方法，其中阻燃SAP颗粒被引入合成树脂，特别是可固化的可热固树脂中。 SAP颗粒最优选用含水阻燃溶液水合。 在这方面，阻燃溶液可以基本上由单独的水或含有一种或多种水溶性无机阻燃剂的水溶液组成。 当SAP颗粒与含水无机阻燃剂溶液水合时，此后可将SAP颗粒干燥以除去基本上水分。 以这种方式，无机阻燃剂将保留为物理夹带在SAP颗粒内的干燥残余物。 因此，SAP颗粒用作其中无机阻燃剂均匀分散的物理基体。 然后可以将SAP颗粒与合成树脂共混，或者可以研磨成更细的颗粒，其含有无机阻燃剂水溶液的干燥残余物，然后与合适的合成树脂混合。

    Abstract: The invention relates to a method of producing a multi-layer, preferably two-layer, sandwich of a foamed polystyrene film with a co-extruded unfoamed film, in particular for further working into labels or shaped bodies utilizing the shrinkability of the films, in which a polystyrene resin composition, together with nitrogen as expansion agent and a pore-former, is extruded out of the nozzle of an extruder and the extruded composition is expanded prior to cooling to below the softening point. In order to obtain a production of foamed polystyrene films which is economical as to material and is as unsusceptible to breakdown as possible and also as insensitive to aging as possible and readily printable, the invention proposes that, as expansion agent, there be used exclusively per kilogram of foamed film 1/30 to 1/50 nitrogen (measured in standard liters) of the weight per unit area of the film (measured in grams per square meter), in combination with a powdered mixture of sodium bicarbonate and citric acid, and that the stiffness/surface-nature of the film be controlled by the expansion ratio.

    Abstract: Stable, emission-free, low-shrinkage, fireproof aminoplastic cellular foams are obtained by using an unsaturated, halogenated polyalcohol in the resin precondensate constituent and a dodecylbenzolsulphonic acid partially esterified preferably with a fatty alcohol and a long-chain polyhydric alcohol, preferably a polyethylene glycol, in the foaming agent hardener consituent. The foams are particularly suitable for building construction and for covering, as well as in the agricultural sector and or oil absorption. For certain of these applications, the resin pre-condensate constituent of the invention can be processed with a conventional foamer hardener constituent or the foamer hardener constituent of the invention can be processed with a conventional resin precondensate constituent.
