Process for the production of polyarenazole polymer |
摘要 |
The present invention concerns a process for making a polyareneazole polymer comprising the steps of: a) contacting azole-forming monomers, metal powder, and optionally P2O5, in polyphosphoric acid to form a mixture; b) blending the mixture at a temperature of from about 50° C. to about 110° C.; c) further blending the mixture at a temperature of up to about 145° C. to form a solution comprising an oligomer; d) optionally, degassing the solution; and e) reacting the oligomer solution at a temperature of about 160° C. to about 250° C. for a time sufficient to form a polymer.
