POLYMER COMPOSITIONS IN SOLVENTS WITH HIGH IGNITION TEMPERATURE, METHOD FOR PRODUCING THEM AND THEIR APPLICATION AS DEPRESSANT ADDITIVES REDUCING THE TEMPERATURE OF FILLING OF OIL, OIL, AND OIL

摘要

The invention relates to polymer formulations comprising at least two different solvents with a flash point 60°C and polymer compositions obtainable by radical polymerization of at least one alkyl(meth)acrylate in the presence of at least one ethylene-vinyl ester copolymer. The invention further relates to a multistage method for producing such formulations and to the use of such formulations as pour-point depressants for crude oils, mineral oils or mineral oil products.
