Patent GB-810331-A (GB)
Title: Process for producing sheet material
IPC: C08J3/18
Filed: 1956-09-18
Abstract: Sheet material is made by mixing a thermoplastic particulate resin with a heat-gellable plastisol paste, forming a layer of the mixture, heating to gel the plastisol and set the mixture, and then further heating and pressing.  The plastisol is made by mixing a finely divided resin, e.g. polyvinyl chloride or copolymers of vinyl chloride with vinyl acetate or diethylmaleate, with a plasticizer therefor, e.g. dibutyl and dioctyl phthalates, tricresyl phosphate polymeric ester type plasticizers and other esters of phthalic, adipic, sebacic, azelaic and phosphoric acids.  The particulate thermoplastic resin may also be a vinyl chloride polymer and may be made by forming a plastisol of the resin, heating to fuse it and then breaking up the fused product into particles.  In preferred processes the particulate resin may be of one or more colours and different effects may be obtained in the finished product depending upon the time in which the resin particles are allowed to stand in contact with the plastisol and absorb plasticizer therefrom; thus flooring material may be produced in which coloured particles are present either in a terrazzo or a spatter pattern.

Title: Preparation of organic acid esters of cellulose
IPC: C08B3/22
Filed: 1952-11-14
Abstract: Organic acid esters of cellulose containing salts which, at temperatures up to 100 DEG  C., can exist in forms having different degrees of hydration and which, in passing from a lower to a higher degree of hydration, undergo a change in specific volume of more than 0.6, are washed with water containing in solution a salt which reacts by double decomposition with the salt initially present in the ester to form salts which either are incapable of existing in forms having different degrees of hydration or, if they are so capable, undergo a change in specific volume of less than 0.6 in passing from the lower to the higher degree of hydration, one of the salts so formed being insoluble or almost insoluble in water.  The change in specific volume refers to the change in volume in c.cm. which occurs on changing the degree of hydration of 1 gram of the salt, reckoned as anhydrous.  Salts in which the above change exceeds 0.6 include sodium sulphate, sodium phosphate, magnesium sulphate and aluminium sulphate. Salts in which the change is less than 0.6 are calcium sulphate, magnesium acetate and sodium acetate.  The salt present in the water used for washing the cellulose ester is preferably a bicarbonate or a water-soluble fatty acid salt of calcium or another alkaline earth metal and the concentration of the salt is preferably 40-75 parts per million, calculated as calcium carbonate.  The cellulose ester may be the acetate, propionate, butyrate, acetate propionate or acetate butyrate.  In an example a washed cellulose acetate flake containing 435 parts per million of magnesium sulphate is washed three times for 20-minute periods at 25 DEG  C. with 12 times its weight of water containing 31.6 parts per million of calcium acetate and dried.  Textile materials and films made from the treated esters are improved in resistance to delustring when washed with hot water.
