    摘要: An improved method for preparing amino polyols is disclosed. The method is the Mannich condensation of phenol, formaldehyde and diethanolamine in a molar ratio of (1:1:1), and then alkoxylation with a mixture of ethylene oxide and propylene oxide in a weight ratio of about 5:95 to 20:80 to form an amino polyol of hydroxyl number 440 to 515.The method gives higher yields of aromatic amino polyols of lower viscosity than those of the comparative example.

    摘要: A method for producing a flexible polyurethane foam from reacting a polyol blend with a polyisocyanate in the presence of a polyurethane formation catalyst is described. The polyol blend contains from 0.5 to 10 wt. % of an aromatic polyester polyol extender typically used in rigid foams. The polyol extender is made from dibasic acids, alkylene glycols and recycled polyethylene terephthalate. Commercial extenders cause flexible foams to shrink, a problem not found in the foams of this invention.

    摘要: Novel amino polyols made by alkoxylating ethylene glycol diamine bottoms products, such as triethylene glycol diamine bottoms products, and tetraethylene glycol diamine bottoms products are described. For example, these bottoms products, alone or together, maybe propoxylated in a non-catalytic reaction to give amino polyols that are useful in producing rigid polyurethane foams. The resultant foams have better K-factors and a higher percentage of closed cells than comparable foams made with conventional amino polyols.
