Patent GB-766585-A (GB)
Title: Improvements relating to polystyrene plastic materials
Inventor: LONG FRANK
IPC: C08F279/02
Filed: 1954-06-18
Abstract: Polystyrene of improved impact strength and flexibility is obtained by polymerizing a 25 per cent solution in styrene of a vulcanizable natural or synthetic rubber, by heating in three stages (a) at 80 DEG to 110 DEG  C. to 20 to 40 per cent conversion of styrene to polystyrene; (b) at a temperature reduced by 3 DEG  to 10 DEG  C. to a 40 to 60 per cent conversion, and (c) at 170 DEG  to 200 DEG  C. until the polymerization is complete.  The rubber may be a natural pale crepe or a cold butadiene-styrene copolymer.  To improve heat dissipation as the viscosity increases the mass may be transferred, e.g. at 5 to 5 per cent conversion, to smaller containers having a relatively large surface areavolume ratio. Catalysts, e.g. benzoyl and dit-butyl peroxides, and t-butyl perbenzoate; lubricants, e.g. butyl stearate, and modifiers such as dodecyl mercaptan may be present.  The polymerization may be carried out with agitation and in a non-oxidizing atmosphere.  The product may be crushed or extruded and chopped into pieces suitable for moulding.ALSO:Polystyrene of improved physical properties is obtained by polymerising a solution in the styrene of up to 25 per cent by weight of the styrene, of a vulcanizable natural or synthetic rubber by heating in three stages (a) at 80 DEG C. to 110 DEG C. to a 20 to 40 per cent conversion of styrene to polystyrene, (b) at a temperature reduced by 3 to 10 DEG C. to a 40 to 60 per cent conversion and (c) at 170 DEG  to 200 DEG C. until the polymerisation is complete.  The rubber may be a natural pale crepe.  Since the viscosity increases as polymerisation proceeds the mass may be transferred at an intermediate stage to smaller containers having a relatively large surface area-volume ratio. Catalysts, e.g. di-t-butyl and benzoyl peroxide, and t-butyl perberzoate; lubricants e.g. butyl stearate, and modifiers such as dodecyl mercaptan may be present and the reaction may be performed in a non oxidizing atmosphere.

Patent GB-589242-A (GB)
Title: Improvements in and relating to the preparation of salts of organic acids
IPC: C07C51/41
Filed: 1944-09-25
Abstract: A process for the production of metal salts of organic acids comprises heating one or more esters of an organic acid in the fluid state with lead, copper, cadmium, zinc, iron, nickel, silver or tin in the presence of water and oxygen.  The process may be carried out (a) by passing oxygen or an oxygen containing gas such as air together with the ester and water (in an amount between 10 and 50 times that stoichiometrically required) into a converter having a high ratio of length to the greatest cross-sectional dimension and containing in fragmentary form the metal to be treated, or (b) by passing the gas into a suitable vessel such as the above described converter charged with the metal particles, ester and water.  During both processes a portion of the fluid material may be removed from the converter and returned thereto at a point remote from where it was removed. In a modification the reaction is effected in a solvent for both the ester and metal salt.  The process is executed at temperatures ranging from 50 DEG C to 200 DEG C and at normal or super atmospheric pressures.  The esters specified are the methyl, ethyl, propyl, higher alkyl, glycerol and glycol esters of acetic, propionic, butyric, caproic, lauric, palmitic, stearic, ricinoleic, melissic glycollic, lactic, tartaric, oxalic, glutaric, adipic, acrylic, methacrylic, oleic, benzoic, and naphthenic acids, and the acids in coconut, corn, cottonseed, rapeseed and similar vegetable oils.

Title: Process and apparatus for producing an extensible web material
IPC: D06C21/00
Filed: 1965-04-30
Abstract: 1,100,908. Shrinking fabric and paper. CLUPAK Inc. 30 April, 1965 [28 July, 1964], No. 18307/65. Headings D1S and D2A.  Apparatus for compacting a web 40 comprises first and second blankets 22, 34 having closed paths of travel, the outer surfaces of the blankets 22, 34 having a portion of their paths of travel in surface to surface relation, a non- rotatable pressure rod 20, 21 within the closed path of each of the blankets 22, 34, which rods 20, 21 are positioned with respect to the blankets 22, 34 to form a nip 35 therebetween, the nip 35 being at a predetermined oblique angle to the direction of travel of the blankets 22, 34, the blanket 22 having a wrap on the rod 20 in one direction of curvature and on the rod 21 in the opposite direction of curvature, and means for feeding the web 40 into the nip 35. The blanket or belt 22 has a deformable surface and may be formed of natural or synthetic rubber. Preferably, it has a strong relatively inextensible layer faced with a readily extensible and contractible layer. The rods 20, 21 extend obliquely across the direction of travel of the blanket 22 and are adjustable towards and away from each other to properly nip the blanket 22 therebetween. The blanket or belt 34 is inelastic, has a low coefficient of friction and is thinner than the blanket 22. Rods 30, 31 are disposed at twice the angle relative to the blanket 34 than the rods 20, 21 are disposed relative to the blanket 22 so that the blanket 34 is directed into the nip 35 in a direction normal to that at which the rods 20, 21 are disposed. The web 40 is passed onto the blanket 34 at a point 41 and is carried over a rod 32 by this blanket. As the blanket passes under the rod 30, the web passes under the rod 31 to eliminate a speed-up thereof. The web 40 passes into the nip 35 and is shrunk in a direction at an oblique angle to the cross-machine direction. Lubricant, e.g. a silicone-water solution, may be directed into the nip area to lower the coefficient of friction between the web 40 and the blanket 34 and to cause a softening of the fibres of the web. In a modification (not shown), the web 40 passes directly into the nip 35 and is not carried thereto by the blanket 34. The web (71), Fig. 9 (not shown), may also be shrunk in the machine direction, as well as at an angle thereto, by a unit (70) as described in Specification 727,261 prior to or after the oblique shrinkage.
