  • Compositions with freeze thaw stability
    Patent number: 9080135
    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.
