Specific mixtures of n,n-bis(2-hydroxyalkyl)-4-toluidine derivatives, their preparation and a method of using such specific mixtures

Preparation of a mixture of two or more N,N-bis-(2-hydroxyalkyl)-4-toluidine compounds (I) comprises reaction of 4-toluidine (containing less than 0.2 wt.% of 3-toluidine) with at least 2 mol of alkylene oxide (per mol of 4-toluidine). Preparation of a mixture of two or more N,N-bis-(2-hydroxyalkyl)-4-toluidine compounds of formula (I) comprises reaction of 4-toluidine (containing less than 0.2 wt.% of 3-toluidine) with at least 2 mol of alkylene oxide of formula (II) (per mol of 4-toluidine). R 1>H or CH 3 (where the two residues of R 1> at direct adjoining carbon atoms does not simultaneously represent CH 3); and n, m : 0-11 (where the sum of n and m is at least 1). Independent claims are also included for: (1) (I) obtained by the method; and (2) a polymer product obtained by radical polymerization of polyester (preferably polyesters) in the presence of (I) as polymerization- or vulcanization accelerator.
