FIELD: production of filled formed pieces based on polymethylacrylate. SUBSTANCE: method to produce filled formed pieces on the base of polymethylacrylate has stages of feeding under stirring of dispersion filler in liquid monomer-bearing medium, addition of radical-forming initiator, mixing of monomer-bearing medium with solid polymer presented in the form of particles, feeding of mixture of monomer-bearing medium and solid polymer presented in the form of particles in polymerization chamber with following polymerization and removal produced formed piece. Method provides, that addition of radical-forming initiator is exercised directly before feeding of the mixture in polymerization chamber. In the case grain filler is used in amount of 30 - 80 % of weight of emulsion formed in the process. EFFECT: increased productivity. |
