Description
По основному авт. св. № 73311 полимеризаци и сополимеризаци ВИНИЛОВЫХ соединений производ тс в водной эмульсии в присутствии желатины, органических кислот, добавки готового полимера дл ускорени процесса солей или окислов железа н при водном модуле 1 :4 и выше.According to the main author. St. No. 73311 polymerization and copolymerization of VINYL compounds are carried out in an aqueous emulsion in the presence of gelatin, organic acids, additives of the finished polymer to accelerate the process of salts or iron oxides n at an aqueous modulus of 1: 4 and above.
Известно также применение SOa, бисульфитов и гипосульфитов как катализаторов при полимеризации виниловых производных, в частности хлорвинила.It is also known the use of SOa, bisulfites and hyposulfites as catalysts in the polymerization of vinyl derivatives, in particular vinyl chloride.
Однако внедрение этого метода требует применени автоклавов из нержавеющей стали и установки целой системы теплоотнимаюшеГ аппаратуры.However, the introduction of this method requires the use of stainless steel autoclaves and the installation of a whole system of heat removal equipment.
Описываемый метод полимеризации и сополимеризации хлорвинила устран ет указанные недостатки и может быть внедрен в производство на осуществл ющем железном оборудОвани. При этом качестве получаемого полимера будет выше качества полимера, получаемого пс известному способу.The described method for the polymerization and copolymerization of vinyl chloride eliminates these drawbacks and can be implemented in production on the implementing iron equipment. In this case, the quality of the polymer obtained will be higher than the quality of the polymer obtained by a known method.
Полимеризацию и сополимеризацию хлорвинила по описываемому методу, при соблюдении условий, изложенных в авт. св. № 73311, осуществл ют следующим образом: процесс ведут при водном Модуле (отношение хлорвинила к воде) 1:1, 1 : 2 и 1:3; перекись водорода или другие перекиси берут в количестве от 0,2 до 1%, а бисульфита «атри илп кали - от 0,1 до 1% по отношению к хлорвинилу; в качестве эмульгатора примен ют желатину, никель или натриевую соль сульфокислоты в количестве от 0,7 до 1,5% к воде.Polymerization and copolymerization of vinyl chloride according to the described method, subject to the conditions set forth in the ed. St. No. 73311, carried out as follows: the process is carried out at a water module (ratio of vinyl chloride to water) 1: 1, 1: 2 and 1: 3; hydrogen peroxide or other peroxides are taken in an amount of from 0.2 to 1%, and bisulfite "atri il potassium - from 0.1 to 1% relative to the vinyl chloride; Gelatin, nickel or sodium salt of sulfonic acid in the amount of from 0.7 to 1.5% to water is used as an emulsifier.
Процесс ведут при температуре от 30 до 50 в зависимости от заданной ВЯЗКОСТИ.The process is carried out at a temperature of from 30 to 50, depending on the specified viscosity.
