Abstract
In this invention, at least two monomers are grafted onto hydroxy-containing cellulose polymer. The invention thus provides a polymer of a cellulose containing a hydroxy group on which is grafted, by replacement of the hydrogen atom of the hydroxy group, with a copolymer having a polymerized lactam-containing moiety and a polymerized quaternized ammonium-containing moiety. The ratio of the polymerized lactam group of the quaternized ammonium moiety in the grafted copolymer can be predetermined to provide polymers which are particularly useful in the hair treatment industry.
