VISCOSITY REGULATING COMPOSITION

摘要

A viscosity regulating composition having a polymeric structure with an internal hydrophobic unit located within the polymer's backbone, multiple hydrophilic units, and terminal hydrophobic units. In one embodiment, the internal hydrophobic unit may have at least three linked hydrophobic segments, of the same or different hydrophobic segments, with the proviso that the multiple hydrophobic segments are not linked to each other by one or more hydrophilic linking segments, for example water-soluble, polymeric groups.

1. A viscosity regulating composition comprising a polymer, said polymer containing an internal hydrophobic unit located within the polymer's backbone; and one or more terminal hydrophobic units covalently connected to said internal hydrophobic unit, wherein said internal hydrophobic unit has multiple hydrophobic segments, wherein said multiple hydrophobic segments are not linked to each other by one or more polyether polyol linking units; and wherein said one or more terminal hydrophobic units contain from 12 to 29 carbon atoms exclusive of the linking group carbon atoms.
