Abstract
Способ стабилизации бутилкаучука на стадии водной дегазации при его выделении из полимеризата введением в последний водной суспензии фосфорсодержащего антиоксиданта, отличающийся тем, что, с целью повышения стойкости бутилкаучука к термоокислительной деструкции, в качестве антиоксиданта используют полимерный фосфит формулыгде n = 4 - 5 в количестве 0,3 - 3,0 вес.ч. на 100 вес.ч. каучука.The method of stabilization of butyl rubber at the stage of water degassing when it is separated from polymerizate by introducing a phosphorus-containing antioxidant into the last aqueous suspension, characterized in that, in order to increase the resistance of butyl rubber to thermo-oxidative destruction, the formula of phosphite containing n = 4-5 is 0, 3 - 3.0 weight.h. per 100 weight parts rubber
