実験手順

About 50 parts by weight of an aqueous sodium silicate solution containing about 15% Na2O and 25% SiO2 by weight, 10 parts by weight of propylene oxide, 2 parts by weight of adipic acid, 0.2 parts by weight of sodium stearate and 0.1 part by weight of benzoyl peroxide are mixed then added to an autoclave and a temperature of about 50° C. is maintained at a pressure between 7.0 and 7.1 kg per cm2. Vinyl chloride monomer is slowly added while agitating over a period of 7 to 10 hours until the emulsion contains about 30% vinyl chloride polymerized with the sodium silicate and propylene oxide thereby producing an emulsion of poly(sodium silicate-vinyl chloride-propylene oxide) copolymer.
