AbstractSynthesis and polymerization ofN‐hexyl‐N‐[2‐(4‐vinylphenyl)ethyl]amine (5) are reported. To elucidate the reaction mechanism for the monomer synthesis, kinetic studies are carried out on the lithium catalyzed amination reaction of styrene (3) and of 1,4‐divinylbenzene (1) with hexylamine (2). The reaction rate,v, was found to be expressed asv=k[3] [2][CH3(CH2)5NHLi], wherekis the rate constant. Methods for selective synthesis of5are considered on the basis of results of the kinetic studies. Polymerization and copolymerization behavior of5shows that5has characteristics similar to3in radical pol
