Abstract of the Disclosure Polymers of meta- and para-compounds of the formula: Image are disclosed. These monoene-amine monomers may be made by acid- catalyzed hydrolysis of the corresponding monoene-isocyanate compounds, followed by reaction with a strong base to form the free amine. Poly(m- or p-isopropenyl-.alpha.,.alpha.-dimethylbenzylamine), and copolymers of m- or p-isopropenyl-.alpha.,.alpha.-dimethylbenzylamine, are disclosed with at least one ethylenically unsaturated monomer copolymerisable therewith. These polymers find use in the sizing of paper, as flocculants, in water classification, and in hair sprays.
