Title: Dispersion Polymerisation.
Inventor: OSMOND DESMOND WILFRED JOHN
IPC: C08F2/08

Abstract: 1,174,391. Polymer dispersions. IMPERIAL CHEMICAL INDUSTRIES Ltd. 20 Jan., 1967 [31 Jan., 1966], No. 4180/66. Headings C3G and C3P. A dispersion of a polymer in an organic liquid is prepared by polymerizing an ethylenically unsaturated monomer in the liquid in the presence of a stabilizing preformed amphipathic graft copolymer, comprising a polymeric component which is solvated by the liquid and a polymeric component which is non-solvated by the liquid, the copolymer being substantially free of ungrafted non-solvated component. The stabilizer may be prepared by adding a random mixture of the graft copolymer and its ungrafted non-solvatable and solvatable components to the liquid in which the dispersion is to be formed and removing the insoluble, non- solvatable component by centrifugation. Alternatively, the graft copolymer is prepared free of ungrafted components by grafting on to a polymer non-solvatable in the said liquid at least 3 polymeric chains which are solvatable, or vice versa, said grafting being carried out in a liquid in which both graft components are soluble. In Example 1, a copolymer of lauryl methacrylate and glycidyl methacrylate is reacted with methacrylic acid, prior to being grafted with a mixture of methyl methacrylate and methacrylic acid. The resulting solution is added to an aliphatic hydrocarbon medium, which is then clarified by filtration or centrifugation prior to polymerization therein of methyl methacrylate and methacrylic acid to produce a polymer dispersion. In Example 2, a methyl methacrylate-glycidyl methacrylate copolymer is reacted with thioglycollic acid and grafted with lauryl methacrylate, the resulting graft copolymer being employed as a stabilizer as in Example 1. The graft copolymer in Example 3 is produced by grafting hydroxyethyl methacrylate on to a styrene-glycidyl methacrylate copolymer reacted with methacrylic acid and is used as a stabilizer in the production of a dispersion of polystyrene. In Example 4, a methyl methacrylate-methacrylic acid copolymer is reacted with glycidyl methacrylate, grafted with lauryl methacrylate and used in the production of a dispersion of methacrylic acidmethyl methacrylate copolymer by a two-stage process employing azobisdiisobutyronitrile as catalyst and octyl mercaptan as modifier. Similarly, copolymer dispersions are produced in Examples 5 to 7, the graft copolymer stabilizers employed being (5) a methyl methacrylateundecenyl methacrylate copolymer grafted with lauryl methacrylate, (6) as in Example 2 and (7) a methyl methacrylate-methacrylyl chloride copolymer treated with ultra-violet light, tertiary butyl peroxide and pyridine prior to grafting with 2-ethylhexyl acrylate. In Example 8, a vinyl acetate-glycidyl methacrylate copolymer is reacted with acrylic acid and grafted with vinyl octoate, the resulting copolymer being employed as stabilizer in the production by a two-stage process of a dispersion of vinyl acetate-acrylic acid copolymer in aliphatic hydrocarbon.

Patent GB-1026942-A (GB)
Title: Treating fabrics
Inventor: JONES RICHARD LEWIS
IPC: D06Q1/00
Filed: 1964-02-01
Abstract: A fabric is finished by selectively treating parts thereof such that in these parts the constituent yarns have a relatively low mutual coefficient of friction compared to yarns in the other parts of the fabric and subjecting the fabric to an abrading operation.  After the abrading process, the fabric is dyed preferably using deep dye shades to obtain good contrast shades. The treatment of the selected parts may be with a "softening agent" in the form of either a viscous textile lubricant, e.g. an emulsion of silicone oil in water, or a surface acting agent. Alternatively, if the yarns are made wholly or partly of a synthetic linear polymer, the molecular structure of the surface layers of those synthetic yarns may be changed.  The "softening agent" may be applied by screen printing and may be thickened, e.g. by a resin, so that the treated parts are sharply defined. Abrasion may be applied by a known sueding machine.  The fabric may be dyed before or after the "softening" and abrading operations.  The fabric may also be scoured and dried or heat set, e.g. on a stenter.  Specified fabrics are Simplex warp-knitted fabrics, weft-knitted fabrics, woven fabrics and pile fabrics. The yarns may comprise staple fibres or continuous filaments. Natural or synthetic fibres or mixtures thereof are specified.  In one example, the "softening agent" used to treat a nylon fabric comprises an emulsion of silicon oil in water and sodium polymethacrylate and in another example, a nylon fabric is treated with polyethoxystearate.
