Abstract
PURPOSE: The reaction between a specific group-containing ethylene oxidealkylene oxide copolyether type polyurethane, a hydroxy-containing polyetherpolyol and water gives the titled foam with a long cream time and a short tack-free time.
CONSTITUTION: (A) An ethylene oxide (EO)-alkylene oxide (AO) copolyether polyurethane prepolymer containing 3W30wt% of 2 or more terminal isocyanates AO:EO=30:70W95:5) is made to react with (B) a primary hydroxyl-containing polyetherpolyol having 2 or more functional groups, polyoxypropylene chains in the middle of the molecular chain and polyoxyethylene chains at the terminals and (C) water where B+C is 1W40% and less than 15% based on A, in the presence of a catalyst and a foaming stabilizer to give flexible polyurethane foam.
USE: Furniture, beddings, cushions for cars, backing for carpets.
