Abstract
Polymers and copolymers of a quaternary monomer, vinylbenzyltrimethylammonium chloride, have been studied. A product similar to that previously obtained by partially chloromethylating polystyrene and aminating with trimethylamine has been made. The product with 15 to 25 mole per cent quaternary groups forms metastable aqueous solutions. Light scattering measurements in the presence of added salt do not indicate aggregation. The quaternary monomer exhibits micellar behavior in conductivity measurements. Copolymers with acrylamide are water‐soluble and substantive to paper pulp; copolymers in minor amount with acrylonitrile are dyeable with acid dyes; copolymers in minor amounts with styrene are clear and free of tendency to pick‐up or maintain a static charge.
