FIELD: chemical industry. SUBSTANCE: present invention describes novel polymers of olefins, more particularly carbon monoxide with one or more α-olefins consisting of linear chains, each having carbon monoxide units and units from one or more α- olefins having 10 carbon atoms per molecule and located essentially in alternating manner, said units having average molecular weight of greater than 104. Present invention also describes method of preparing polymers of olefins. The claimed method allows for high reaction rate and makes it possible to obtain novel compounds which can be used as addition agents to hydrocarbon paraffin oils. EFFECT: improved properties of oils when used at low temperatures.
