摘要

Improvements in the object of the main patent No. 196 721, by "a process for the regeneration of polymethacrylic resins, with simultaneous obtaining of pearly polymethacrylates", essentially characterized by the fact of effecting the regeneration in particular of methyl methacrylate, of formula ** (See formula) ** with aggregation of fillers, dyes and pearlescent products, in molding and polymerizing this methacrylate, between glass or metal plates of which one of them is provided with reliefs or patterns that provides irregularity to the molding face, subjecting the loaded mold to the action of ultraviolet light or heat, subsequently demolding; in taking this polymerized plate as the face of a new mold, leaving the irregular face inside and pouring between it and the metal or glass plate that makes up this mixed mold the methacrylate with or without fillers, which adapts to the bottom of the irregularities, causing in it a polymerization that transfers to the irregular face a soldering re-polymerization that gives rise to an intimate union without solution of continuity, resulting in plates in which a smooth and translucent face allows to see in different shades the color background of the first plate.
