Insitu molecular composites based on rigid-rod polyimides

摘要

A polymer which can undergo thermally-induced transformation to provide a reinforcing component and a matrix component. This polymer has repeating units of the formula: ##STR1## wherein Z is selected from the group consisting of dialkyl amino thermoplastic moieties and dialkyl amino moieties which can undergo insitu reaction to form a thermoset. Dialkyl amino moieties which can undergo insitu reaction to form thermosets include the following: ##STR2## wherein Q is ##STR3## R is -- CH.sub.3 or Q and a has a value of 1 to 3. Dialkyl amino thermoplastic moieties include the following: ##STR4##PPThe invention described herein may be manufactured and used by or for the Government of the United States for all governmental purposes without the payment of any royalty.
