摘要：
An aqueous viscoelastic composition is provided comprising at least one viscoelastic surfactant and at least one hydrophobically modified polymer which is formed from polymerization of ethylenically unsaturated monomers has a number average molecular weight of from 1 000 to 100 000 Da and to a level of at least 0.1 mole% based on the amount of monomer units in the polymer contains monomeric units each covalently bonded to a pendant optionally alkoxylated hydrocarbyl group having from 6 to 40 carbon atoms said pendant optionally alkoxylated hydrocarbyl group being connected to the backbone of said hydrophobically modified polymer via a non ester containing linking group.
