| abstract |
A meta- or para-compound of the formula:n wherein: X⊖ is an anion selected fromthe group consisting of R 4 OSO 3 ⊖ Cl⊖, Br⊖ and ⊖;n wherein: n is 2 or 3;n R 1 , R 2 and R 3 which may be the same or different, are lower alkyl; and R 4 is lower alkyl or allyl. n Also disclosed is a method of making the compound by reacting meta- or para-isopropenyl-a,a-dimethylbenzyl isocyanate with either an amino alcohol or a dialkylamino- ethyleneamine, and quaternizing the reaction product with an alkylating agent. The compound may be polymerized with a co-monomer such as acrylamide to yield water-soluble cationic polymers for use in water clarification, flocculation, and hair spray applications. |
