This polymer is readily available with a variety of va contents generally ranging from 0 to 40.
Poly ethylene co vinyl acetate solubility.
Poly ethylene co vinyl acetate vinyl acetate 40 wt.
Not only the solubility parameter and the vinyl acetate content but also the molecular weight and polydispersity have an important influence on both phase behavior and pour point depression.
Furthermore it was confirmed that the additive must present a reduced solubility at a temperature close to the crude oil cloud point.
