  • Patent number: 7488830
    Abstract: A polymer that includes at least one monomeric unit having a pendant substituent group according to formula (II): wherein: R1 is H, chloro, bromo, alkyl, hydroxyalkyl, aryl, or aralkyl, R2 and R3 are each independently H, alkyl, hydroxyalkyl, aryl, aralkyl, uriedo, or carboxyalkylene, R4 is alkylene or R5, R7, and R10 are each independently alkylene, R6, R8, and R9 are each independently H or alkyl, A is O or N—R11, provided if A is O and R4 is methylene, then R1 cannot be H, chloro, or bromo, R11 is H or alkyl, and X? is an anion, is useful in personal care application, such as hair styling compositions.
