Versuchsvorschrift
661.9 g of the ethylene oxide polyether started from trimethylolpropane esterified with 2 mol acrylic acid (12 mol ethylene oxide per mol trimethylolpropane) and 164.4 g of a polyester polyol from hexanediol and adipic acid (OH number 314, equivalent weight 178.5 g), 1.0 g 2,6-di-tert-butyl-4-methyl-phenol and 1.0 g tin octoate were initially introduced into the reaction vessel. 148.8 g Desmodur® T80 (toluylene diisocyanate, commercial product of Bayer AG, Leverkusen) were metered in at 50 to 60° C. After a further 5 h 31.6 g isophorone-diisocyanate were metered in. The reaction was carried out at 60° C. for a further 5 h and 74.0 g of the ethylene oxide polyether started from trimethylolpropane esterified with 2 mol acrylic acid (12 mol ethylene oxide per mol trimethylolpropane) were then added. The reaction was subsequently carried out at 60° C. until the NCO content of the solution was less than 0.10 wt. %.
