The invention relates to meta and para compounds of the formula I and their acid salts. These monoeneamine compounds can be prepared by the acid- catalyzed hydrolysis of corresponding monoene-isocyanate compounds and subsequent reaction of the intermediates with a strong base, in order to form the free amine. Compounds of the formula I can form poly(m- or p- isopropenylene-α, α-dimethylbenzylamines and copolymers of m- or p-isopropenyl-α, α- dimethylbenzylamine which can be used for sizing paper. <IMAGE>
