METHOD OF PRODUCING GRANULES FROM WASTES OF COPOLYMERS OF ETHYLENE WITH VINYL ACETATE Russian patent published in 2024 - IPC B29B9/00 C08J3/12 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of chemical industry, in particular to a method of processing wastes of copolymers of ethylene with vinyl acetate in order to obtain granules, which will find wide application, for example, in production of shoes, sheets of various applications or purposes. Disclosed is a method of producing granules from wastes of copolymers of ethylene with vinyl acetate, which consists in mixing initial components, as which are selected dust from wastes of copolymers of ethylene with vinyl acetate, sevilen, stearic acid, liquid paraffin and peroxide. Then the mass is heated to temperature of 125–130 °C. Then the mass is rolled and cut into pieces, which are mixed at temperature of 80–90 °C and moulded into granules. Sevilen of grades 11808-340, or 11306-075, or 12306-020 is selected.

EFFECT: invention provides reduction of time and energy consumption for implementation of the method and reduction of negative impact on environment.
