Abstract

La presente invención se refiere a empleo de tipos de copolímeros seleccionados de esteres de los ácidos acrílicos y/o metacrílico como mejoradores de la fluencia en petróleos y fracciones de petróleo (I) ricas en parafina, especialmente de copolímeros constituídos por esteres del ácido acrílico y/o metacrílico de alcoholes superiores o bien fracciones alcohólicas con al menos 16 átomos de carbono en el resto alcohólico y no más del 5 por ciento en peso, preferentemente del 0,5 al 2,5 por ciento en peso de anhídrido maleico (por ciento en peso referido al peso del copolímero) como mejoradores de la fluencia en aceites en bruto ricos en parafina y/o fracciones de petróleo con puntos de fluencia propios situados por encima de los 25 grados C, para reducir su punto de fluencia a valores situados por debajo de 15 grados C, preferentemente por debajo de 10 grados C.
