Polyoxyalkylene polyether amino alcohols containing a tertiary hydroxyl group and flexible polyurethanes made therefrom.

摘要

Polyoxyalkylene polyether amino alcohols are prepared which have the following formula: <CHEM> Wherein, R represents hydrogen or a methyl or an ethyl group, x represents a number having an average value of about 1 to about 4 and n represents a number having an average value of about 1 to about 40. These alcohols may be further modified by reaction with an epoxy resin to form an adduct. The polyoxyalkylene polyether amino alcohol is prepared by alkoxylating a glycol that contains one tertiary hydroxyl group and also a primary or secondary hydroxyl group in order to form an alkoxylated intermediate and by then reductively aminating the alkoxylated intermediate. These products are used in the production of polyurethanes and polyurethane foams.
