Mixture of polyarylalkane oligomers A and B of formula with n, and n 2 = 0, 1 and 2, knowing that n, + n 2 ≤ 3 with n ' 1 n ", and n 4 = 0, 1 and 2 n' 2 , n" 2 , n 3 and n 5 = 0 and 1 knowing that n ' 1 + n " 1 , + n' 2 , + n" 2 + n 3 + n ' 3 , + n 4 + n 5 ≤ 22n n n These mixtures are obtained by the action of a halide or a mineral acid on a product of radical chlorination of toluene. |
