Abstract
A method of making microporous synthetic resinous material comprises compacting a mixture of a synthetic resin, e.g. vinyl chloride, and silica hydrogel, both in particulate form, shaping (see Group V) and heating the mixture to a temperature at least as high as the fusion point of the resin, cooling the shaped mixture whilst still under pressure and thereafter releasing the shaped mixture. The compacting pressure may be sufficient to prevent the evaporation of water contained in the silica hydrogel, which water may be evaporated from the shaped mixture, after the release of compacting pressure, by heating to a temperature insufficient to alter the microporous structure of the resin. The preferred synthetic resin is hard gamma vinyl chloride which may be copolymerized with e.g. up to 15 per cent of a monoethylenically unsaturated monomer such as vinyl acetate or vinylidene chloride. Other resins are copolymers of vinyl chloride with polyethylene, polystyrene, polyacrylonitrile or polymethyl acetate. An example of a mixture (parts by weight) is polyvinyl chloride powder 100, dibasic lead silicate sulphate 16, silica hydrogel 300. Specification 532,475 [Group V], is referred to.
