  • Non isocyanate polyurethane foams
    Patent number: 10450416
    Abstract: A curable isocyanate free formulation for preparing a polyurethane foam. The formulation includes a compound A chosen from multifunctional cyclic carbonates of a formula (I) or a mixture thereof, a compound B chosen from multifunctional cyclic carbonates containing oxyalkylene groups —OR3- of a formula (II) or a mixture thereof, a compound C chosen from multifunctional amines of a formula (III) or a mixture thereof and a compound D chosen from non-reactive blowing agents, as well as a process for preparing a non-isocyanate polyurethane foam, a foam obtainable by this process, compound B, a mixture of compounds A and B, the use of compound B for enhancing the solubility of a non-reactive blowing agent in a compound A and a foamable system having a first part A containing compound A and compound B and a second part B containing compound C, wherein part A and part B are preferably physically separated.
