Patent GB-582649-A (GB)
Title: Improvements in and relating to the manufacture and production of hollow articles from a thermoplastic cellulose derivative
IPC: C08L1/08
Filed: 1944-08-03
Abstract: Hollow articles are obtained by heating flatshaped pieces of a thermoplastic composition consisting of 100 parts by weight of cellulose acetate having an acetyl content between 52 and 55 per cent or ethyl cellulose having an ethoxy content of about 48.6 per cent, 5 to 30 parts of a plasticiser and 10 to 25 parts of a solvent in an enclosed space at a temperature above the boiling point of the solvent.  The heating, which may be effected in a stove or oven, causes the solvent to vaporize and inflate the shaped pieces. Dimethyl phthalate or triacetin are suitable plasticisers for the acetate and tricresyl phosphate for ethyl cellulose, acetone being a suitable solvent in each case.  The flat-shaped pieces are obtained by rolling the thermoplastic mass containing an excess of solvent into sheets at a temperature below the boiling point of the solvent. The solvent is thus reduced to the desired amount and the shaped pieces are cut or punched from the sheet.  The shaped pieces may take the form of squares, circles or rectangles and the hollow articles obtained therefrom may be employed as buoyancy packing material. Alternatively, pieces shaped like birds, animals and reptiles can be inflated to provide toys.  Examples of the process are given.
