Title: Manufacture of polymerization products
IPC: C08F14/06
Filed: 1936-09-28
Abstract: Gaseous monomeric compounds capable of polymerization with the aid of a per - compound, such as a salt of a per-acid or an organic peroxide, as polymerization accelerator, e.g. vinyl chloride, vinylmethyl ether, ethylene oxide or butadiene, are polymerized by causing the gaseous monomeric compound to ascend in the form of fine bubbles, in the presence of such polymerization accelerator, through a column of liquid in which it is insoluble or only partially soluble, the dimensions of the bubbles and length of the column being such that the bubbles contact with the liquid for a time sufficient to secure an adequate degree of polymerization.  Water and paraffinic hydrocarbons are suitable liquids to which are added suitable polymerization accelerators, e.g. an alkali persulphate or perborate, or acetyl, benzoyl or oleyl peroxide; the liquid may contain a proportion of solvent. The rising of the bubbles may be retarded by using a liquid of high viscosity, e.g. aqueous solutions of polyvinyl alcohol, gelatin or hydrooxyethyl cellulose.  In an example, vinyl chloride is introduced through a fine nozzle at the lower end of a spiral column filled with a 1 per cent aqueous solution of potassium persulphate maintained by a jacket at 50-60 DEG  C., any unreacted monomer being returned to the column.  After the desired concentration of polymer is attained, the emulsion is coagulated with sodium chloride and the polymerizate filtered with suction and washed.  In a second example, the spiral column is omitted, the vinyl chloride being introduced through a filter candle of kieselguhr.  In a further example, vinyl acetate is introduced together with the vinyl chloride.  The Specification as open to inspection under Sect. 91 includes also the subject-matter of Specification 482,647.  This subject-matter does not appear in the Specification as accepted.

[Also in Group XXIX] A method of forming a lens in a transverse passage 14 of a metal fitting 11 having a longitudinal fluid flow passage, includes closing one end of the passage 14 by supporting the fitting on a refractory support 20 with a thin sheet 19 of glass arranged between the support 20 and the fitting 11, Fig. 2, depositing a pellet of hard glass on the sheet 19 and heating the assembly until the pellet is melted into a pool 22 which when cooled comprises a lens 23 and subsequently cooling the fitting to a temperature below the strain point of the glass. The molten glass of the pool 22 is pressed into a predetermined desired form by a plunger 30. A thin sheet of glass is next arranged on a support such as 20 and a pellet of soft glass arranged on it and covered by the open end of the passage 14. The pellet is then melted to form the lens 24. The sheets of glass 19 unite with the glass pools to case the exterior surfaces of lenses. The glass sheets 19 are of lower expansion glass than the pools. The excess of glass of the sheets 19 cool at a greater rate than the portions in union with the lenses and thermal stresses cause the glass to break away from the lenses along their border regions. Alternatively glass sheets of the same size as the passage 14 may be employed. In this case a support 50 holds the sheet within the passage 14 to effect its union with the pool wholly within the confines of the passage. Glass frit coating 17, 18 are given to the surfaces of the passage 14 prior to forming the lenses. A suitable hard glass for the lens 23 is composed of 40 per cent. SiOz, 50 per cent.
