<p>Use of a carrier material comprising functional groups at its surface, which are reactive towards isocyanate groups, for reducing the proportion of isocyanate groups exhibiting monomers in compositions comprising at least one isocyanate groups exhibiting polyurethane polymer and at least one isocyanate groups exhibiting monomer, is claimed. Independent claims are also included for: (1) a composition comprising at least one isocyanate groups exhibiting polyurethane polymer, at least one isocyanate groups exhibiting monomer, and at least one carrier material exhibiting functional groups on its surface, which are reactive towards isocyanate groups, where the functional groups of the carrier material are reacted at least partially with isocyanate groups of the isocyanate groups exhibiting monomer; (2) reducing the proportion of isocyanate groups exhibiting monomer in the compositions containing at least one isocyanate groups exhibiting polyurethane polymer and at least one isocyanate groups exhibiting monomer, comprising providing the composition, and combining the composition with a carrier material exhibiting functional groups on its surface, which are reactive towards isocyanate groups; and (3) a hardened composition obtained by reacting the above composition with water.</p> |
