Claim 0:
1. An accelerator for a reactive resin system, prepared by reacting the following components:
(1) an aromatic primary or secondary amine, or a mixture thereof having the structure:, where
R1 is selected from the group consisting of chlorine, bromine, pseudohalogen, C1-20 alkyl, hydroxy-C1-20 alkyl, C2-20 alkenyl, hydroxyl C2-20 alkenyl, C2-20 alkynyl, hydroxy C2-20 alkynyl and phenyl;
m=0-3; and
R2 is selected from the group consisting of H, C1-C20 hydroxy-C1-C20 alkyl, C2-C20 alkenyl, hydroxy-C2-C20 alkenyl, C2-C20 alkynyl, hydroxy-C2-C20 alkynyl and aryl;
(2) a diglycidyl ether of a diol or polyol, which has 2 to 20 C atoms; and
(3) an α,β-unsaturated carboxylic acid, selected from the group consisting of branched and unbranched C2-C10-α,β-unsaturated carboxylic acids,
wherein an opening of the epoxy groups present in the diglycidyl ether leads to formation of glycerol bridges between the amine and the diol and between the α,β-unsaturated carboxylic acid and the diol, which results in a finished accelerator.
