SYNTHESIS OF ORGANIC POLYMERIC SYSTEMS CAPABLE OF WITHSTANDING TEMPERATURES GREATER THAN 900 F
Abstract
The major objective of this work is the synthesis of organic polymeric systems that have exceptionally high thermal stability i.e., the ability to withstand temperatures greater than 900 F. Several types of polymer systems investigated, which includes polyesters and polyamides, indicated exceptional promise. One aromatic polyamide, in particular, synthesized by interfacial polycondensation process withstood muffle furnace temperatures as high as 1100 F with no softening at or below this temperature. Color change increased when temperature was raised from 920 F to 1060 F in a 15 minute period. From 1060 F to 1100 F in a 25 minute period the polymer became a blacker brown.
