| description | The present invention relates to a method for the production of an isotropic polymeric network comprising multifunctional molecules with a functionality of at least 5 by reacting in a solvent the multifunctional molecules with a coupling agent, wherein the coupling agent is present in an amount which is sufficient to couple the multifunctional molecules to at least 5 other multifunctional molecules and wherein the sum, p , of the amounts of the multifunctional molecules and coupling agent per unit of volume, in kg/m , is at least equal to the value as given by expression (I) a(m1 + n DIVIDED 2m2) DIVIDED 10 (d+L) in which a = 0.2 d = the diameter of the multifunctional molecule, including the length of the bonds to the middle of atoms of the coupling agent to which it is attached. L = the length of the coupling agent, measured between the middle of the atoms that are connected to the multifunctional molecule. m1 = the molecular mass of the multifunctional molecule as present in the isotropic polymeric network m2 = the molecular mass of the coupling agent as present in the isotropic polymeric network n = the functionality of the multifunctional molecule ( n ≥ 5) The invention furthermore relates to an isotropic polymeric network with a density lower than 1000 kg/m and a specific Young's modulus of at least 0.01 GPa.m /kg, shaped articles hereof and the use of the isotropic polymeric network as construction material |
