| PROPERTIES |
PFA is highly crystalline and has poor mechanical properties. The crystalline polymer has a high melting point and is insoluble in common organic solvents. These properties make it difficult to process using solvent casting, microencapsulation techniques, and injection molding. Compression molded samples tended to crumble when immersed in an aqueous environment. Polymerization with citraconic acid was tried as a means for improving these properties. Unfortunately, a cyclic monomeric anhydride was formed using either the solution or melt polymerization methods
