COMPOSITION FOR IMPROVING LOW-TEMPERATURE PROPERTIES OF LIQUID FUEL OR LUBRICATING OIL, COMPOSITION OF LIQUID FUEL OR LUBRICATING OIL, AND ADDITIVE CONCENTRATE

摘要

FIELD: chemistry of polymers. SUBSTANCE: present invention describes two or more transistorized ethylene- unsaturated ester copolymers. Each copolymer is transistorized by at least partial hydrolysis for removing acid groups or by treatment with the same acid for partial reduction of ester groups. EFFECT: improved properties of the composition. 11 cl, 3 tbl
