发明名称 Process for the continuous preparation of melt processable polyurethanes with improved softening behaviour
摘要 A process for the continuous preparation of melt processable polyurethane elastomers having improved softening behavior is disclosed. The process entails reacting a polyisocyanate, a polyol and a chain extender, which have a temperature of at least 170° C., in a static mixer, wherein the reaction mixture is prepared. The reaction mixture is then metered into an extruder into which optional auxiliaries and/or further components are fed.
