    摘要: A method of making a hydroxyl terminated precursor for polyurethane is disclosed. The method comprises heating a vegetable oil-polyol mixture of modified vegetable oil containing about two or more hydroxyl groups per molecule and a polyether polyol having about two or more hydroxyl groups per molecule at a temperature of at least about 25 degrees Celsius and at a pressure of about 1 atmosphere. The mixture has a hydroxyl equivalent ratio of about 1:1 vegetable oil to polyol. The method further comprises mixing for at least about 10 minutes an isocyanate containing about two or more isocyanato groups per molecule at least about 25 degrees Celsius to the vegetable oil-polyol mixture at a molar equivalent ratio of at least 2:1 vegetable oil-polyol mixture to isocyanate to react the isocyanate with the mixture to form the hydroxyl terminated precursor.

    摘要: A method of making an isocyanato terminated precursor for polyurethane is disclosed. The method comprises heating an isocyanate containing about two or more isocyanato groups per molecule at a temperature of up to 80 degrees Celsius and at a pressure of about 1 atmosphere. The method further comprises mixing a modified vegetable oil comprising about two or more hydroxyl groups per molecule with the isocyanate at a molar equivalent ratio of at least 2:1 isocyanate to vegetable oil for a predetermined time period to form the isocyanato terminated precursor.

    摘要: Allophanate-modified MDI which is a storage stable liquid at 25.degree. C. is produced by reacting a monoisocyanate and an organic material having at least two hydroxyl groups and a molecular weight of from about 60 to about 6,000 to form a urethane. The urethane is then reacted with and isomeric mixture of MDI in an amount such that the product isocyanate will have an NCO content of from about 12 to about 30%. The isomeric mixture of MDI is composed of 4,4'-diphenylmethane diisocyanate containing from 0 to about 60% by weight 2,4'-MDI and less than 6% by weight of the 2,2'-MDI. This allophanate-modified MDI is further reacted with an organic isocyanate-reactive material to produce an allophanate-modified MDI prepolymer containing urethane, urea and/or biuret groups having an NCO content which is generally from about 5 to about 29% by weight. The prepolymers of this invention are particularly useful in reaction injection molding processes because they give molded articles having improved flex modulus.
