Abstract

Una dispersión de un éster polímero en al menos un liquido,teniendo dicho éster polímero una espina hidrocarbonada y al menos un primer tipo de cadena lateral que es un grupo alifático de cadena larga de por lo menos 14 átomos de carbono, y especialmente al menos un segundo tipo de cadena lateral que es un alquilo de 1-13 átomos de carbono, en donde el polímero está presente dicha dispersión en una cantidad de por lo menos 10% con preferencia de 20-30% en peso. Las dispersiones son de menor viscosidad que las correspondientes soluciones de los polímeros en hidrocarburos y se pueden usar para reducir o inhibir la deposición de cera en aceites céreos, por ejemplo, en crudos de petróleo.
