摘要
A method of making polymer articles from thermosetting polymers, the polymer articles being selected from fibers and films, and the method comprising the steps of: providing a prepolymer blend of a thermosetting polymer, the prepolymer mixture being in a fluid state and the prepolymer mixture can be activated by means of energy, so that the prepolymer mixture, when the prepolymer mixture is brought into contact with an energy source, undergoes an irreversible chemical transformation, so as to form a post-reaction polymer; Extruding the prepolymer mixture through at least one meltblowing die into a gas stream to form the polymer article; wherein the meltblowing nozzle is in communication with a cold gas stream which maintains the prepolymer mixture at a temperature at which less than 10% of the crosslinking potential occurs within 1 minute, and contacting the polymer article with an energy source after the prepolymer mixture mixes the nozzle the energy source left the prepolymer mixture to form ...
