摘要： The invention relates to the use of non-dendrimeric, highly functional, hyperbranched polymers as demulsifiers for cracking crude oil emulsions. The hyperbranched polymers are preferably hyperbranched polycarbonates, hyperbranched polyesters, hyperbranched polyethers, hyperbranched polyurethanes, hyperbranched polyurea polyurethanes, hyperbranched polyureas, hyperbranched polyamides, hyperbranched polyether amines and hyperbranched polyester amides that comprise functional groups, selected from the group including -OC(O)OR, -COOH, -COOR, -CONHR, -CONH 2 , -OH, -SH, -NH 2 , -NHR, -NR 2 , - SO 3 H, -SO 3 R, -NHCOOR, -NHCONH 2 and -NHCONHR, wherein R represents an optionally substituted alkyl or aryl group.
