Abstract:
1. A process for producing a polyurethane foam comprising the steps of: providing at least one organic polyisocyanate; providing a first polyol compound, wherein said polyol having a functionality in the range of 2 to 8 and a hydroxyl number in the range of 20 to 100; providing an autocatalytic polyol compound 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 said autocatalytic polyol being an amine initiated polyol obtained by alkoxylation of at least one initiator molecule selected from the group consisting of 3,3′-diamino-N-methyldipropylamine, 2,2′-diamino-N-methyldiethylamine, 2,3-diamino-N-methyl-ethyl-propylamine, 3,3′-diamino-N-methyldipropylamine or a mixture thereof; continuously merging together said organic polyisocyanate, said first polyol, and said autocatalytic polyol compound in the presence of a blowing agent and optionally one or more additives; optimizing the reaction conditions via adjusting the weight percent ratio of said autocatalytic polyol compound to said first polyol compound in a range of 1:99 weight percent to 5:95 weight percent, based on the total weight of said autocatalytic polyol compound and said first polyol compound; and thereby producing a flexible polyurethane foam.
