a substantially inert atmosphere application_number US 2647598 A description this invention includes several different processing steps that result in the effective preparation of a superior coated fabric such coated fabrics being suitable for such uses in upholstery convertible tops truck covers outdoor furniture tarpaulins ground cloths roofing conveyor belts gaskets wallcovering curtains book coverings clothing awnings signs tents luggage shoes and the like the exact details of the these steps are tailored for the general nature of the application process these application processes include spread coating melt calendering extrusion and other ways know to one skilled in the art the basic components involved in the preparation of the fluid are preformed polymers polymerizable liquids initiators and optionally a wide range of additives such as fillers fibers blowing agents fire retardants processing aids impact modifiers dyes pigments and the like the use of an initiator is needed for this invention when thermal or photochemical curing is desired the curing process involves the free radical polymerization of the liquid initiators are not essential if high energy radiation such as electron beams gamma rays or other forms of high energy radiation are used to cause the curing to occur a particularly useful procedure for the preparation of this fluid is to add the initiator after all other components have been combined and thoroughly mixed most desirably under inert conditions adding the initiator in a liquid form to the polymer monomer fluid and obtaining a uniform mixture by a low.
