Abstract: The present invention relates to demulsifying and dehydrating formulations of heavy crude oil based block copolymers amine bifunctionalized with low polydispersities. These formulations can contain solvents whose boiling point is in the range from 35 to 200° C., preferably: dichloromethane, chloroform, toluene, xylenes, turbosine, naphtha or mixtures thereof.
