Abstract

NEW MATERIAL:A dimer of a p-isopropenylphenylisocyanate shown by the formula I (R is a group shown by the formula II or III; R1 is H or CH3).
EXAMPLE: 4-Methyl-2,4-bis(4'-aminophenyl)-penta-2-ene.
USE: An intermediate for a urethane polymer useful as a cushioning material, constructional material, synthetic rubber, covering material, etc.
PROCESS: A p-isopropenylaniline is heated to give a dimer of a p-isopropenylaniline shown by the formula IV, which is reacted with phosgene in an inert solvent, e.g., benzene, dichloromethane, chloroform, etc. at 0W50°C, to give a compound shown by the formula I.
