FIELD: chemistry.
SUBSTANCE: invention concerns mix with activated initiation agent, which can be applied in obtaining polyalkylenepolyenes. Claimed mix with activated initiation agent includes (a) at least one initiation agent activated in advance and comprised by: (i) at least one of first initiation agents with equivalent mass of at least 70; (ii) at least one epoxide; and (iii) at least one DMC-catalyst; and (b) at least 2 mol % per quantity of initiation agent(s) activated in advance of one of second initiation agents with equivalent mass less than equivalent mass of first initiation agent.
EFFECT: elimination of necessity to synthesise expensive initiation agents with high molecular mass with catalysis facilitated by potassium hydroxide in separate assigned reactor.
