Description
Способ полимеризации метилметакрилата в присутствии органических перекисей и иолиметилитаконата .кали или способ полимерпзан) в присутствии органических перекисе и полиакриловых кислот ие исключает комковани иолимера иа стеиках раекциопного аппарата, что затрудн ет промышленное ведение нроцееса и влечет за собой известные иотерн иродукта.The method of polymerization of methyl methacrylate in the presence of organic peroxides and iolimethyl itaconate (potassium) or the method of polymerization in the presence of organic peroxide and polyacrylic acids does not clump the iolimer with the x-rayics of the x-ray apparatus, which makes it difficult for the industrial management of nococes and entails the well-known io product.
По иредлагаемому сиособу полимеризаци метилметакри; ата проводитс в присутствии лерсульфата кали , аммопи и натри с введением в реакционную массу казеина, что исключает указанные недостатки и вызывает выделение полимера по мере его полимеризации.According to the proposed method of polymerization of methyl methacry; Ata is carried out in the presence of Lersulfate potassium, ammopi and sodium with the introduction of casein into the reaction mass, which eliminates these drawbacks and causes the release of the polymer as it polymerizes.
П р и мер: 100 ч. мономера с плacтифпкaтopo i c ieшивaioт с 300 ч. воды, в смесь нри помешивании ввод т 0,25% персульфата аммопи и 0,25% казеина в виде щелочного раствора при рН выше 8. нагревают и при перемешивании выдерживают при температуре 70-80 в течение 3-5 часов. Выпавший мелкий гранулированный полимер от 1ывают н сушат обычным способом.P and measures: 100 parts of monomer with plastic sifter ic, i.e. with 300 parts of water, 0.25% ammopi persulfate and 0.25% casein as an alkaline solution with a pH above 8 are added to the mixture by stirring. maintained at a temperature of 70-80 for 3-5 hours. The precipitated fine granulated polymer from 1 is dried and dried in the usual way.
Предмет изобретени Subject invention
Способ полимеризации метилметакрилата в водной среде в присутствии персульфата аммони , кали или натри , отличающийс тем, что, с целью устранени образовани комков полимера на стенках аппарата, процесс полимеризации ведут в присутствии щелочного раствора казеина при рН выше 8.A process for the polymerization of methyl methacrylate in an aqueous medium in the presence of ammonium, potassium or sodium persulfate, characterized in that, in order to eliminate the formation of polymer lumps on the walls of the apparatus, the polymerization process is carried out in the presence of an alkaline casein solution at a pH above 8.
