PRODUCTION PROCESS FOR A THERMOPLASTIC RESIN-BASED CAST PLATE

摘要

a method according to which, in a first step, wean elastomeric latex prepared by oil in water emulsion, in the presence ofat least one ionic surface active agent, at least oneu00e9thylu00e9niquement unsaturated monomer; and then, in a secondis added to the obtained latex and at least one monomervinyl, insoluble in water, and slightly soluble inwater and neutralizing the ionic charges are brought by theby adding to the latex, latex and monomer mixture ata transfer agent with ionic chargesopposite to those of the surfactant used in the first stage.in order to achieve the transfer of latex particles in thevinyl monomer; and in a third step, we separatethe aqueous phase, the organic phase containing the latexthe vinyl monomer; and a fourth stepcarries out the bulk polymerization of the organic phase.between the two plates of a mold resistant temperaturethe reaction mixture and the maximum non reactive or insolublethe contact of the liquid charge, so as to achieve thethe casting after cooling and mold release plate. the inventionthe plate is also obtained by this method. thisprocess for economically and quicklysolution of the monomer (s) of the matrix containing the latex.solution it is then sufficient to polymerize by a techniquecasting.
