Patent ID: 8637624

Claim:
A polymer comprising: one or more first monomeric units each comprising at least one bicycloheptyl- or bicycloheptenyl-polyether radical, and one or more second monomeric units each comprising a branched (C 5 -C 42 )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 (C 1 -C 6 )alkyl groups per ring carbon atom, and wherein the monomeric units each further comprise at least one polymerizable functional group selected from acrylo, methacrylo, acrylamido, methacrylamido, diallylamino, allyl ether, vinyl ether, α-alkenyl, maleimido, styrenyl, and α-alkyl styrenyl groups.
