STUDY OF THE RHEOLOGICAL PROPERTIES OF AQUEOUS SUSPENSIONS OF ANTIOXIDANT 2246.

Results of an experimental study are presented which show that aqueous suspensions of the antioxidant without previous grinding or the addition of surface-active agents have fairly large particles and unsatisfactory kinetic stability and resistance to aggregation. The use of surface-active agents and stabilizers improves the properties. Changing the temperature from 10 to 50 C reduces the effective viscosity of aqueous suspensions of the antioxidant by approximately 50%. In the production of light butadiene-styrene (methyl-styrene) rubbers rosin soaps are suitable stabilizers for the aqueous suspensions of antioxidant 2246, and for the production of butadiene-acrylonitrile rubbers sodium alkylsulphonate is a suitable stabilizer for the antioxidant suspension.
