Compositions of hydrocarbons from refining, having improved fluidity at low temperatures. |
摘要 |
<p>The fluidity at low temperatures of compositions based on liquid hydrocarbons from refining is improved by means of the addition, preferably in solution, of ethylene/propylene/(conjugated diene) copolymers or terpolymers, containing 20-55% of propylene, optionally degraded by thermo-oxidation, and structurally characterized by values of at least one of X2 and X4 parameters, which are equal to, or lower than, about 0.02, indicative of the absence in the polymeric chain of propylene linking inversions.</p> |
