Abstract
The invention relates to linear copolymers of monomer units having both ammonium groups and polysiloxane groups. Amine oxide groups may be substituted for ammonium groups. The polymer backbone includes side chains having high densities of quaternary ammonium groups. The copolymers impart softening, antistatic, quick-drying and setting properties in the appropriate settings.
