Process for the production of polyurethane foams |
| abstract |
The present invention relates to a process for preparing flexible, semi-flexible or rigid polyurethane foam plastics from a polyfunctional isocyanate and a polyhydric compound. More specifically, the invention involves the substitution of some portion of the hydroxy groups on the polyhydric with acetoacetate groups. Such substitution reduces the viscosity of the polyhydric resin without affecting the performance properties of the foams. Various substitution levels can be used depending on the desired level of viscosity reduction. |
