Abstract
Preparation techniques of multifunctional additives from textile industry wastes were developed. The possibility of their use in the production of synthetic rubbers was considered. Promising technological methods of modification of emulsion rubbers with powdered cellulose additives through their input at various stages of the production of elastomeric compositions were proposed. It was established that it was expedient to introduce multifunctional additives in the form of dispersions with a solution of the coagulating agent. Peculiarities of the effect of multifunctional additives on elastomeric compositions were revealed. It is shown that the application of multifunctional additives for the modification of styrene-butadiene rubber allowed reducing the consumption of the coagulant and acidifying agent, lowering an ecological load on the environment, as well as reducing the duration of drying rubbers due to a dominant acceleration of its final stage.
