  • Rheology modifier polymer
    Publication number: 20110243873
    Abstract: A polymer includes (a) one or more first monomeric units, each independently comprising at least one bicycloheptyl-polyether, bicycloheptenyl-polyether or branched (C5-C50)alkyl-polyether group per monomeric unit, wherein the bicycloheptyl-polyether or bicycloheptenyl-polyether group may optionally be substituted on one or more ring carbon atoms by one or two (C1-C6)alkyl groups per carbon atom, and (b) one or more second monomeric units, each independently comprising at least one pendant linear or branched (C5-C50)alkyl-polyether group per monomeric unit, provided that the first and second monomeric units cannot both comprise a branched (C5-C50)alkyl-polyether group and is useful as a component in liquid compositions, such as aqueous latex coating compositions, personal care compositions, home care compositions, and institutional or industrial care compositions.

  • COMPOSITIONS WITH FREEZE THAW STABILITY
    Publication number: 20110223125
    Abstract: Composition including freeze thaw stability polymer such as a copolymer having a weight average molecular weight of at least about 30,000 grams per mole, a blend of a first polymer and a second polymer, a crosslinked alkali swellable acrylate copolymer, or at least one polymerizable reactive alkoxylated acrylate monomer. The copolymer has one or more first monomeric units and one or more second monomeric units. The one or more first monomeric units each independently including at least one bicycloheptyl-polyether, bicycloheptenyl-polyether or branched (C5-C50)alkyl-polyether group per monomeric unit. The bicycloheptyl-polyether or bicycloheptenyl-polyether group may optionally be substituted on one or more ring carbon atoms by one or two (C1-C6)alkyl groups per carbon atom. The one or more second monomeric units each independently including at least one pendant linear or branched (C5-C50)alkyl-polyether group per monomeric unit.

  • Compositions having hase rheology modifiers
    Publication number: 20100273683
    Abstract: A monomer compound that contains at least one polymerizable functional group per molecule, and at least one bicycloheptyl-, bicycloheptenyl-, or branched (C5-C42)alkyl-polyether radical per molecule, wherein the bicycloheptyl- or bicycloheptenyl-polyether radical may optionally be substituted on one or more of the ring carbon atoms by one or two (C1-C6)alkyl groups per ring carbon atom is useful in making polymers, particularly pH responsive polymers.
