  • Stable dispersions of polyhydrazodicarbonamides useful in the preparation of polyurethane products having improved load-bearing capacity
    Patent number: 5342855
    Abstract: This invention relates to a process for the preparation of stable dispersions of hydroxyl-containing polyhydrazodicarbonamides in a hydroxyl-containing compound. The dispersions are prepared by the reaction of organic isocyanates, isocyanate-reactive compounds having a molecular weight in the range from 400 to 10,000, relatively low molecular weight isocyanate-reactive compounds, and hydrazines or hydrazides. This invention further relates to the dispersions prepared by said process, the use of the dispersions to prepare polyurethane foams having exceptional hardness, and the foams prepared thereby.

  • Purification of acetylene-terminated polyimide oligomers
    Patent number: 4307220
    Abstract: A process for purifying an acetylene-terminated polyimide oligomer containing residual solvent in which the oligomer is initially dissolved in the same solvent used as the reaction medium in its synthesis. After precipitating the oligomer from solution by mixing with an aqueous solution of potassium or sodium chloride, the precipitated oligomer is washed successively with a plurality of liquids of decreasing polarity to provide an oligomer free of residual solvent.
