    Abstract: In a fiberboard composed of fibers bound together with a starch derivative produced by reacting maleic, phthalic, or succinic anhydride, or a combination of these anhydrides, with starch, an improvement in the Fourdrinier process for producing said fiberboard wherein the reaction product of the anhydride and starch is directly mixed, without drying, with fiber and other conventional ingredients, such as clay, and is then passed directly to the Fourdrinier machine.

    Abstract: The invention relates to a process for preparing paper or cardboard in which starch and a mineral filler are incorporated into cellulosic fibres. The process uses a blend, which is prepared under specified conditions, of raw starch and starch phosphate. The procedure for incorporating the starch blend and the mineral filler into the cellulosic fibres is also specified.

    Abstract: A fire resistant vermiculite composition board comprises, in percent by weight, from 40 to 90% heat expanded vermiculite particles; from 5 to 20% ceramic clay particles; from 10 to 30% hydrated cellulosic gel having a TAPPI drainage time of at least 900 seconds; from 1 to 20% defiberized wood; and from 1 to 20% starch. The vermiculite is in an incompletely expanded condition of a degree predetermined to permit its further expansion upon subsequent exposure to heat. This results in a corresponding expansion of the composition board of which it is a component when the board is exposed to fire, preventing the formation of cracks and insuring continued fire protecting coverage of the area across which the board is applied.

    Abstract: Starch ether derivatives are prepared by reacting a starch base with N-(2-haloethyl)iminobis(methylene)diphosphonic acid or with a N-(alkyl)-N-(2-haloethyl)aminomethylphosphonic acid. The derivatives contain aminophosphonic acid groups (or their salts) as zwitterion substituents which consist of either one or two anionic methylene phosphonic acid groups bound to a cationic nitrogen. Their cationic or anionic characteristics may be increased by introducing suitable cationic or anionic groups either by simultaneous reaction with the aminophosphonic acid reagent or by consecutive reaction either prior to or subsequent to the aminophosphonic acid reaction. They are especially useful as pigment retention aids in paper making processes.
