Or by the reaction of allyl chloride with Hexamine. Pure samples can be prepared by hydrolysis of allyl isothiocyanate. It behaves as a typical amine. Polymerization can be used to prepare the homopolymer (polyallylamine) or copolymers. The polymers are promising membranes for use in reverse osmosis.
