ты формулы H-G-fi-CH CH-C-OCjHj в аце тоне перемешивают в смесителе. По окончании перемешивани отгон ют растворитель, а остаток прогревают при 50 С, после чего смесь размалывают в шаровой мельнице. Получают карбонат кальци , модифицированный моноэфиром малеиновой кислоты с содержанием модификатора 1% от массы карбоната кальци .Formulas H-G-fi-CH CH-C-OCjHj in an acetone are mixed in a mixer. After stirring, the solvent is distilled off, and the residue is heated at 50 ° C, after which the mixture is ground in a ball mill. Calcium carbonate modified with maleic acid monoester with a modifier content of 1% by weight of calcium carbonate is obtained.
Дл определени степени прививки полимера к поверхности частиц полученного наполнител провод т в его присутствии суспензионную полимеризацию метилметакрилата. Степень прививки полимера определ ют путем экстракции несв занного польшера ацетоном в приборе Сокслета с последующим анализом неэкстрагируемого остатка на содержание поли 1етилмет- акрилата.In order to determine the degree of grafting of the polymer to the surface of the particles of the resulting filler, the suspension polymerization of methyl methacrylate is carried out in its presence. The degree of grafting of the polymer is determined by extracting the unbound polser with acetone in a Soxhlet instrument, followed by analyzing the unextractable residue for poly (methyl methyl acrylate).
