COMPOSITIONS BASED ON ETHYLENE-VINYL ACETATE COPOLYMERS AND THEIR USE AS ANTI-GELLING ADDITIVES OF PARAFFINIC CRUDE OILS |
摘要 |
A polymeric composition suitable for lowering the Pour Point of paraffinic crude oils comprising a synergic mixture including at least two ethylene-vinyl acetate copolymers respectively having an average molecular weight Mw lower than 130,000 Dalton (measured via GPC), a content of vinyl acetate monomer ranging from 15 to 50% by weight, with the proviso that the content of vinyl acetate monomer in the respective copolymers differs from one copolymer to another, by over 5%, on a weight basis. |
