Suitable organic solvents are methanol, ethanol, propanol, isopropanol, butanols, ethylene, propylene and butylene glycols and glycerine; if desired the solvent may contain up to 20 per cent of water.  Protective colloids specified are poly-N-vinyl pyrrolidone, a copolymer of vinyl pyrrolidone and methyl acrylate, a copolymer of styrene and maleic anhydride, a copolymer of vinyl pyrrolidone and methacrylamide and polyvinyl methyl and ethyl ethers. Polymerization is preferably accelerated by the use of catalysts such as benzoyl, p-chlorbenzoyl, cyclohexanone, lauroyl and di-tert.-butyl peroxides, tert.-butyl hydroperoxide, azo-bis-(isobutyronitrile), p - chlorphenyl - azo - triphenylmethane, p - chlorphenyl - azo - tri - p - tolylmethane, phenyl - azo - tri - p - anisylmethane, o - nitrophenyl - azo - biphenylmethane, m-chlorphenyl - azo - triphenylmethane, alphanaphthyl - azo - triphenylmethane and phenyl-azo - triphenylmethane.

Patent GB-674865-A (GB)
Title: Improvements in and relating to pigmented coating compositions
IPC: C09D7/65
Filed: 1948-12-23
Abstract: The tendency of a pigmented resinous coating composition to exhibit pigment flotation is decreased by adding thereto from 0.000001 to 0.01 per cent by weight of the coating composition, of the product of hydrolysis of the compound <FORM:0674865/IV (a)/1> where X is a halogen atom.  Pigmented coating compositions specified include oil-modified alkyd resins, either alone or in combination with amido-aldehyde resins, e.g. urea-formaldehyde, and melamine-formaldehyde resins; esters or ethers of cellulose, e.g. ethyl cellulose and cellulose acetate; nitrocellulose; oil-modified phenol-aldehyde resins, e.g. oil-modified paratertiary butyl phenol-aldehyde resins; acrylic acid ester resins; and chlorinated rubber.  The alkyd resins may be made by reacting one or more polyhydric alcohols, e.g. ethylene-, diethylene- and propylene glycols, glycerine, sorbitol and pentaerythritol, with or without monohydric alcohols, e.g. alkyl ethers of ethylene and diethylene glycol, with a polycarboxylic acid (or anhydride), e.g. oxalic, malonic, succinic, adipic, phthalic, tetrachlorophthalic, 4-chlorophthalic and isophthalic acids, and one or more modifying oils, e.g. non-drying, semi-drying, drying, and fatty oils and fatty oil acids, derived synthetically or from vegetable or animal sources, glycerides of fatty acids, and mixtures of one or more of these modifiers with natural resins, e.g. linseed, chinawood, castor, soya bean and oiticica oils, linseed oil acids, coconut oil acids, palmitic, stearic and oleic acids.  The modifying ingredients may be used in amount from 5 to 70 per cent by weight of the total ingredients in the reaction mixture.  Pigments specified are: carbon black, lamp black, ferric oxide, titanium dioxide, lithopone, ferric hydroxide, zinc chromate, zinc oxide, lead carbonate, lead chromate, manganese silicate, ferric ferrocyanide, sulphates and arsenates, and they are used, e.g. in amount from 0.1 to 4 parts by weight of the resin.  In the example, the hydrolysis product of bis-(dimethylchlorosilyl)-methane was isolated and dissolved in toluene to make a 1 per cent (by weight) solution.  One per cent of this solution was added to a castor-oil modified glyceryl phthalate alkyd resin modified with 20 per cent by weight of a butylated melamine-formaldehyde resin and pigmented with titanium dioxide and iron blue.  Other silanes specified are bis-(dimethylfluorosilyl)-methane and bis-(dimethylbromosilyl)-methane.ALSO:Bis-(dimethylchlorosilyl) methane is made by heating trimethylchlorosilane with anhydrous aluminium chloride in a steel hydrogenation bomb and fractionating the resulting liquid.  The corresponding fluorine and bromine compounds may be similarly made.  The compounds have the general formula <FORM:0674865/IV (b)/1> wherein X is a halogen atom.
