METHOD FOR PRODUCING LOW-MOLECULAR AETHYLENE VINYLAZETATE COPOLYMERS |
| abstract |
A process for the preparation of low molecular weight ethylene-vinyl acetate copolymers to improve the flow behavior and the pour point lowering of middle distillates, in which the preparation using free-radical initiators at temperatures of 313 to 473 K and pressures of 50 to 500 bar, wherein the copolymer has an average molecular weight (Number average) of '500 to 5000 and a Vinylazetatgehalt of 10 to 60 Ma.-S has. The polymerization is carried out so that the complex step of separation of solvent and polymers is avoided. The solvents used are those hydrocarbon-containing solvents in the boiling range of the middle distillates, to which the polymer is added later as an additive. The polymerization can be carried out either batchwise or continuously in one or more cascaded polymerization autoclave or in a tubular reactor. The polymerization regulators used are substances which are either incorporated or can be easily and easily removed after the reaction has ended. |
