    Abstract: A process for producing resilient, flexible polyurethane foams that function well in noise and vibration absorption applications for vehicle applications that are made from a blend of polyols (i) and an isocyanate (ii), wherein the blend of polyols (i) comprises a mixture of polyether polyols (i.a) that each has a hydroxyl equivalent weight of from 1200 to 3000 and at least 70% primary hydroxyl groups, from 5 to 80% by weight of the ethylene oxide-capped polypropylene oxides are nominally difunctional, from 0.5 to 20% by weight of the ethylene oxide-capped polypropylene oxides have a nominal functionality of four or higher, and the balance of the ethylene oxide-capped polypropylene oxides, but not less than 1.5% by weight thereof, are nominally trifunctional; an autocatalytic polyol (i.b) having a functionality in the range of 2 to 8 and a hydroxyl number in the range of 15 to 200, wherein said autocatalytic polyol compound comprising at least one tertiary amine group; and a low unsaturation polyol (i.c) having a functionality equal to or greater than 2, a hydroxyl equivalent weight of from 1800 to 2800, and a total unsaturation value of equal to or less than 0.06 meq/g.
