| abstract | 249,600. British Celanese, Ltd., (American Cellulose & Chemical Mannufacturing Co., Ltd.). Dec. 24, 1924. Plastic compositions containing cellulose esters, ethers, &c.-Moulding powders having a basis of organic or inorganic esters or ethers of cellulose are made by treating the pulverized cellulose derivative with water, incorporating a softening agent and a volatile diluent which is not a solvent for the cellulose derivative, and finally evaporating the water and diluent from the powder. As softening agents, any known or suitable high boiling solvent or plasticiser may be used, a list of such being given in the Specification. The softener may be dissolved or suspended in the volatile diluent. Fillers, dyes, resins, stabilizers may be incorporated during or after the treatment. According to an example, 100 lbs. of cellulose acetate ground to a fine pawder are mixed with an equal weight of water. 30 lbs. of triacetin dissolved in 100 lbs. of benzol is added and mixed for about two hours. Gentle heat is applied to evaporate the benzol and most of the water, and the powder is taken from the mixer and dried off. The powder is moulded under pressure and heat into articles such as gramophone records. |
