REACTION PRODUCTS OF ANILINES WITH BISPHENOLIC EISES OF BISPHENOL A PROCESS FOR THEIR PREPARATION AND THEIR USE AS HARDNESS ACCELERATORS

摘要

Cpds. of formula (I) are new, where A = -(p-phenylene)-CR4R5-(p-phenylene)-; R1 = 1-6C alkyl or cycloalkyl, opt. with inert substits., and R1 is Et if n = 0; R2, R3 = H, 1-6C alkyl or cycloalkyl, or halo, and R2 is Me if R3 is H, and R3 is Me if R2 is H; R4, R5 = Me, or R4 + R5 may form an opt. substd. cyclohexane ring together with the C atom between the aromatic rings; R6, R7 = as for R2, R3, but with (cyclo)alkyl gps. opt. contg. inert substits.; m = 1-3; n = 0-2; both m, n may be whole nos. or fractions (statistical average). Also claimed is prepn. of (I) by reacting an amine of formula (II) with a diepoxide of formula (III) in a mole ratio of (II):(III) = (1.25:1)-(2:1) at 100-250 degrees C. In the formulae R1-R7, n = as before; A = -(p-phenylene)-CR4R5-(p-phenylene)-; and p = 0-2 (whole no. or fraction as above).
