The present invention relates to a thickeners that are the polymerization product of a monomer mixture comprising: (a) at least one C3 to C30 olefin; (b) at least one monomer that contains at least one carboxylic acid group; (c) at least one ethylenically unsaturated ester monomer; and (d) one or more crosslinking compounds. Optionally, the above multi-purpose polymer compositions can further include any combination of one or more of: (e) at least one functional monomer; (f) at least one associative hydrophobic monomer; and/or (g) at least one chain transfer agent (CTA) and/or at least one polymeric stabilizer. The thickeners of the present invention are useful in a variety of products including, but not limited to, personal care products, health care products, household care products, institutional and industrial care products, and industrial applications. 1. A thickener composition that is the reaction product of the polymerization of a monomer mixture comprising:(i) (a), (b), (c), and (d);(ii) (a), (b), (c), (d) and (e);(iii) (a), (b), (c), (d) and (f);(iv) (a), (b), (c), (d) and (g);(v) (a), (b), (c), (d), (e) and (f);(vi) (a), (b), (c), (d), (e) and (g);(vii) (a), (b), (c), (d), (f) and (g); or(viii) (a), (b), (c), (d), (e), (f) and (g),{'sub': 3', '30', '1', '18, 'where (a) is at least one Cto Colefin; (b) is at least one monomer that contains at least one carboxylic acid group; (c) is at least one ethylenically unsaturated ester; (d) is one or more crosslinking compounds; (e) at least one functional monomer selected from one or more functional monomer compounds selected from one or more hydroxy(C-C)alkyl(meth)acrylates, one or more open chain and/or cyclic N-vinylamides (N-vinyllactams containing 4 to 9 atoms in the lactam ring moiety, wherein the ring carbon atoms optionally can be substituted by one or more lower alkyl groups such as methyl, ethyl or propyl), one or more amino group-containing vinyl monomers, one or more vinyl esters of aliphatic carboxylic ...
