Title: Polyvinyl oxo-alkanals
IPC: C08F8/28
Filed: 1957-07-17
Abstract: In the process of the parent Specification for producing polyvinyl alkanals by reacting 1 mol. of a polyvinyl alcohol or ester (e.g. the acetate or propionate) with 0.1-1.0 mols. of a C8-C16 oxo-aldehyde, substantially linear products are obtained by performing the reaction in the presence of a heterocyclic compound, having oxygen in the heterocyclic ring, which is a mutual solvent for the polyvinyl alkanal and both of the starting materials.  Specified solvents are dioxane, C1-C4 alkylated dioxanes, dioxolane, and C1-C3 alkylated dioxolanes.  Catalysts for the reaction are hydrochloric, sulphuric and phosphoric acids.  At the end of the reaction the polyvinyl alkanol is precipitated by adding a mixture of an alcohol and water and, after washing with a similar solvent mixture, is dried in vacuo. The polyvinyl alkanal is soluble in the oxygen-containing heterocyclic compounds mentioned above and also in benzene, toluene, xylene, mineral spirits, chloroform, trichloroethane, carbon tetrachloride and carbon disulphide, and may be compounded with plasticizers, e.g. dioctyl phthalate, didecyl phthalate, dioctyl adipate or trioctyl phosphate, or with anti-oxidants, pigments, dyes or fillers. Cross-linking may be effected by reaction with a diisocyanate or diisothiocyanate.  The polyvinyl alkanals may be used in the manufacture of moulded products, adhesives, coating compositions or fibres.  For the last purpose, the polyvinyl alkanals may be melt-spun by feeding them into a screw extruder heated to 200 DEG  C., extruding through a fine aperture held in a vertical plane and taking up the filament on a drum revolving at a speed sufficient to stretch the filament.  Alternatively, they may be wet-spun by dissolving them in dioxane or other solvent specified above and passing the solution through a spinneret into a coagulating bath containing, for example, a mixture of water and methanol maintained at room temperature.  They may also be dry-spun by spinning a solution in the oxygen-containing heterocyclic compound into a heated gas.  The resulting fibres may be cold-drawn.

Abstract: 478,135. Roofs. GREIS, T. July 10, 1936, No. 19227. Convention date, July 11, 1935. [Class 20 (iv)] [Also in Group XIII] The joints, grooves, or junctions between the individual members of a roof covering are packed with shaped elements made of glass-wadding. " Glass-wadding " is defined as a mass of glass fibres which may be produced by a centrifuging process and are so curled and entangled with each other that an elastic cushion like cotton-wadding is formed. A roof formed of courses of tiles 6 ... 15, as shown in Figs. 1 and 2, is provided, below each course, with a course of glass-wadding plates 18 shaped as isosceles triangles. The lower edges of the plates 18 lie on the upper edges of the tiles in the next lower course and coincide with the lower edges of the tiles disposed on the plates. The bisector of the vertex angle of each plate 18 is arranged to lie beneath the centre line 20-20 of the overlap of the two tiles lying on the plate. The upper edges of the plates are bent over on to the faces of the tiles disposed on the plates, and are squeezed between these tiles and the tiles in the next higher course whereby the space formed where four tiles meet is filled. Where the packing is to serve also for insulating the roof, it is in the form of courses of overlapping rectangular plates which are arranged, as shown in Fig. 3, so that their lower edges coincide with the lower edges of the course of tiles on which they are placed. The upper edges 32 of the plates are bent over on to the faces of the said tiles so that they coincide with the position of the lower edges of the tiles in the next upper course and of the underlying plates thereof. In the modification shown in Fig. 6, shaped elements in the form of packing strips 44 are arranged in grooves 45 which are provided in the tiles in a direction parallel to the battens, and the tongues 46 of the tiles in the next higher course are pressed into these packings. These packing strips may be extended so as to form an insulating layer under each course of tiles. The shaped packings may be used on roofs which are covered with flat or curved tiles, zinc plates, or boards.
