Abstract (en)

[origin: WO9916806A1] The present invention is a process for preparing polyurethane polymers by extruding a free flowing liquid polyurethane (TLP). A TLP is prepared from a polyisocyanate and a polyol at low temperature. Elastomeric polyurethane polymers can be obtained from the TLP by a reactive extrusion process. Elastomeric polyurethane polymers thus obtained can be re-processed as a melt (melt processed) a number of times, and the polymer formed into various useful forms.
