Abstract
Procedure for the preparation of new polyglycidyl ethers of the formula **(See formula)** in which R stands for an alkyl, alkenyl, hydroxyalkyl or haloalkyl radical with 1 to 20 carbon atoms; R'represents a hydrogen, chlorine, bromine atom or an alkyl or alkenyl radical with 1 to 20 carbon atoms; R'' means a hydrogen atom or the methyl group; A represents an alkylene radical with 2 to 12 carbon atoms; x means the number 1 or 2; z means the number 0 or 1; p means an integer valued at least from 1 and preferably from 1, 2 or 3; and the sum (y + z) is an integer worth 2 at least and 4 at most, in addition to the group or groups of the formula **(See formula)** they are in ortho and/or para position with respect to the phenolic ether group, characterized by condensing a hydroxymethyl phenolic ether of the formula **(See formula)** in which the symbols R, R', R'', x, y, z and p have the same meaning as in formula (I) and the group or groups -CH2-OH they are in ortho and/or para position with respect to the phenolic ether group, in the presence of alkali metal hydroxide, with a stoichiometric excess of epichlorohydrin or betamethyl-epichlorohydrin and to exclude from the reaction mixture, by means of aceotropic distillation, the water that is in it or that is being formed in it.
