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.
