Abstract

533,746. Synthetic resin resin compositions.. CARBIDE & CARBON CHEMICALS CORPORATI0N. Nov. 21, 1939, No. 30464. Convention date, Dec. 15, 1938. [Class 2 (iii)] Plasticized compositions are prepared by precipitating a thermoplastic synthetic resin from solution by addition of a miscible non- solvent, cashing freefrom solvent, and agitating with a compatible plasticizer in suspension in a non-solvent for both resin and plasticizer. There are specified : resins-polyvinyl resins, e.g. acetals, partial acetals, interpolymers of vinyl halides with vinyl esters of aliphatic acids, polystyrene, polyacrylates and polymethacrylates, and polymerized hydrocarbon resins ; non-solvents-water. Examples show the plasticizing of (1) a polyvinyl partial butyraldehyde acetal with triethyleneglycol di(2-ethyl-butyrate) ; (2) polyvinyl chloride-acetate with dibutyl phthalate; (3), (4) polyvinyl partial formaldehyde or acetaldehyde acetals with diethyl phthalate. Reference is made to moulding the compositions, e.g. by extrusion, and their use as sheets, e.g. in safety glass.
