  • Polyurethane foams incorporating alkoxylated aromatic diamine and acetylenic glycol
    Patent number: 4743628
    Abstract: This invention relates to crosslinker systems for polyurethane foams and a process for producing such foams. The polyurethanes are prepared by reacting an organic polyisocyanate with an organic compound having active Zerewitenoff hydrogen atoms, e.g., a polyol with an alkoxylated aromatic diamine crosslinker and an acetylenic glycol. Improved properties can be achieved, such as, higher load-bearing at equivalent foam density; higher tear; higher elongation and higher air flow.
