Abstract
A process for preparing substantially rigid sheets and the like, comprising passing a fluid composition consisting of a polymerizable organic monomer between two mobile surfaces and in contact therewith, passing said composition and said movable surfaces through at least one region in wherein said composition is subjected to conditions that cause said monomer to polymerize, and separate the resulting polymerized sheet from said two surfaces, characterized in that the path of said surfaces through said zone is defined by the natural curvature of said movable surfaces and because they have an inclination with respect to the horizontal by means of which the fluid pressure exerted by said fluid composition is sufficient to maintain the separation between said surfaces at a predetermined distance, said surfaces being joined to a sufficient degree to compensate for any contraction of the surface. the c during the polymerization so that said surfaces are kept in contact with said composition during the polymerization, and separating the resulting polymerized sheet from said two surfaces.
