Verfahren zum Formen von Folien, Fasern und Basisgeweben aus duroplastischen Polymeren

摘要

A process for forming fibers, films and fibrous webs from thermoset polymers is disclosed. The process includes first forming an energy activatable prepolymer composition. The prepolymer composition is extruded through a die in order to form polymeric articles. Once extruded through the die, the prepolymer composition is then contacted with an energy source which causes the prepolymer composition to irreversibly undergo a chemical transformation to form a thermoset polymer. The cured polymeric articles can then be collected onto a surface and used as desired. The energy source used to activate the prepolymer composition can be, for instance, a heated gas stream, ultra sonic sound waves, or a radiation source.
