Process for removing undesired material from desired material |
| abstract |
In the present invention there is described a process for removing undesired material from desired material in the presence of water. The invented process is characterized by bringing these materials into contact with a prepolymer containing isocyanates, the prepolymer is brought into reaction with at least a portion of water under formation of flexible foam and the foam is removed from the desired material, whereby said prepolymer is then mixed with 2 to 100 parts by weight of water per one part by weight of the prepolymer and at the latest 20 seconds prior its bringing into contact with the indicated materials. In the present invention there is also described the use of water as an agent reducing viscosity of the aforementioned prepolymers. |
