    摘要: 6-chromanol derivatives are used as antioxidants in polyethers. These, particularly in conjunction with other antioxidants, provide excellent protection against oxidation at very low levels of use. They are particularly useful in polyethers for preparing polyurethane slabstock foam.

    摘要: Polyurethane and vinyl polymer composites are rapidly prepared without the requirement of the application of an external source of heat by the admixture of a composition comprising(A) a polyether polyol having an equivalent weight of 30-250, such as an adduct of glycerine with propylene oxide;(B) an organic polyisocyanate, such as toluene diisocyanate;(C) an ethylenically unsaturated monomer, such as styrene;(D) a catalyst for polymerizing ethylenically unsaturated monomers such as tertiary butyl perbenzoate; and(E) a catalyst for urethane formation such as lead octoate.Foams may also be prepared by adding an appropriate foaming agent.
