Reaktionsschritte

41.9 parts by weight of hexane-1,6-diol are melted together in powder form at about 85° C and then treated at 130° C with 583 parts by weight of a hydroxyurethane with a hydroxyl content of 6% by weight obtained from 1 mol of hexane-1,6-diol, 0.7 mol of 1,1,1-trimethylolpropane, 1.8% by weight of caprolactam and 1.3 mol of tolylene diisocyanate (mixture of isomers 2,4 : 2,6 = 80 : 20) to form a highly fluid melt which can easily be stirred. Its viscosity is about 320 cP at 105° C.
