СПОСОБ ПОЛУЧЕНИЯ ПОЛИИМИДА И ПОЛИИМИД, ПОЛУЧЕННЫЙДАННЫМ СПОСОБОМ |
摘要 |
A method for preparing a polyimide includes introducing a mixture of an oligomer and a solvent to an extruder, removing solvent via at least one extruder vent, and melt kneading the oligomer to form a polyimide. The polyimide has a low residual solvent content. The method is faster than solution polymerization of polyimides, and it avoids the stoichiometric inaccuracies associated with reactive extrusion processes that use monomers as starting materials. |
