Abstract

"COPOLìMEROS ACRìLICOS COMO ADITIVOS PARA A INIBIçãO DO DEPóSITO DE PARAFINAS NOS óLEOS BRUTOS E COMPOSIçõES QUE OS CONTêM". Copolímeros de N-vinilpirrolidona e de acrilatos e/ou de metacrilatos de alquilas comportando de 10 a 50 átomos de carbono com distribuições particulares das cadeias são utilizáveis como aditivos para a inibição do depósito de parafinas e a melhoria das propriedades de escoamento dos óleos brutos. Composições contendo os óleos brutos de petróleo e esses aditivos.
