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.
Claims14
A cellulosic graft polymer containing cellulose units having at least one hydroxy group therein on which is grafted, by replacement of the hydrogen atom of said at least one hydroxy group, with a copolymer having a polymerized lactam-containing moiety and a polymerized quaternized ammonium-containing moiety.
A cellulosic graft polymer containing cellulose units having the formula:
- ##STR9## wherein R.sub.5, R.sub.6 and R.sub.9 are selected from hydrogen, lower alkyl, lower hydroxyalkyl, lower alkoxyalkyl, carboxymethyl and carboxymethyl lower hydroxyalkyl, wherein at least one of R.sub.5, R.sub.6 and R.sub.9 is hydrogen which is replaced by at least a polymerizable lactam-containing moiety and a polymerizable quaternized ammonium-containing moiety.
A cellulosic graft polymer having the general formula:
- Cell--O-[(L).sub.1 (Q).sub.q ]
- where Cell is a cellulosic residue, L is a lactam moiety and Q is a quaternized ammonium moiety.
