  • Publication number: 20110009512
    Abstract: A tertiary amine, such as a tertiary amine catalyst that is useful in the production of polyurethanes, may undergo decomposition, which may result in the production of undesirable products. These tertiary amines, however, may be treated with a primary amine containing material to reduce the presence of the undesirable products to an acceptable level. Thus, a foam made from a treated tertiary amine will also have a reduction in the presence of the same undesirable products.

  • Patent number: 5373028
    Abstract: In a method of preparing a poly-urethane and/or -urea foam from a formulation including (a) a polyisocyanate, (b) an isocyanate-reactive component, and (c) a visible emissions producing component, wherein (a), (b) and (e) are reacted under reaction conditions sufficient to form a poly-urethane and/or -urea foam and the foam is then cooled, whereby visible emissions are emitted during cooling, an improvement comprising including in the formulation a visible emissions reducing agent, such that the amount of the visible emissions is reduced as compared with the amount emitted by a foam prepared from a formulation which does not contain the visible emissions reducing agent but which is otherwise substantially similar. Foams prepared therefrom exhibit reduction in visible emissions during the cure period, which is particularly evident when the foams are mechanically cooled. They also exhibit generally good physical properties.
