This invention relates to novel foam modifiers which can be used to prepare flexible foams. These novel foam modifiers provide improved processability and improved properties of the resultant flexible foams. The present invention also relates to the process of preparing these flexible foams and to the resultant foams.

Clear, amine-initiated polyether polyols are made by epoxidizing an amine in the presence of an alkali metal hydroxide catalyst. By reducing the amount of catalyst used during the polyol synthesis and by adding the catalyst after between 5 and 30% of the total amount of at least one alkylene oxide has been added, after lactic acid neutralization, gives a short chain polyol that has foam processing characteristics similar to the conventional sulfuric acid neutralized polyol. The polyols produced in this manner are particularly useful for the production of polyurethane and polyisocyanurate foams.
