Abstract
A method of polymerizing a composition comprising a mixture of monomers said monomer mixture containing from 3 to 100% of amines containing two or more allyl groups which method comprises irradiating a solution of a hydrofluoride, hydrochloride or sulphate salt of said amine in a non polar and non hydroxylic solvent with electromagnetic radiation having a wavelength greater than 180 nanometers and preferably less than 800 nano meters preferably in the presence of a radiation sensitizer at a temperature in the range from -80.degree. to +120.degree. C preferably 10.degree. C to 90.degree. C and isolating the polymer so formed.
