Abstract

1460792 Continuous casting MITSUBISHI RAYON CO Ltd 7 Jan 1974 [18 Jan 1973 (2)] 23531/76 Heading B5A The disclosure is the same as that of Specification 1,460,791, but the claims relate to a process of moulding a methyl methacrylate polymer plate for polymerization in the working space formed by two endless belts and edge sealing means running in compliance therewith, in which polymerization takes place in two successive zones, the first zone being water cooled and at a lower temperature than the first, and the water adhering to the belts and seals is removed before the second zone to prevent blemishes on the surface of the moulded plate.
