Beschreibung
Zusammenfassung:	Hydrophobically modified, hyperbranched polyesters obtainable by a 2-step process of reacting a mixture comprising at least a polyol comprising at least 3 hydroxy groups and a monomer comprising one carboxylic acid group and at least two hydroxy groups, thereby obtaining a hyperbranched polyester comprising terminal hydroxy groups and at least partly esterifying the terminal hydroxy groups with a mixture of carboxylic acids comprising at least linear saturated aliphatic carboxylic acids groups and branched saturated aliphatic carboxylic acids groups. Formulations comprising hydrocarbons and such polyesters and to the use of such hydrophobically modified, hyperbranched polyesters or formulations thereof, as pour-point depressant or wax inhibitor for crude oil.
