The synthesis and evaluation of polymers is an area of major research effort. Of special interest is the preparation of thermally stable polymers having heterocyclic rings as part of the backbone chains. Thermally stable organic polymers are widely used in today's technology because of their engineering advantages. These advantages include their processability, corrosion, radiation and thermal resistance, and low cost. Compared to metal alloys they also offer a drastic reduction in weight without significant reduction in mechanical strength, thereby increasing fuel efficiency and payload.
Polymer resins lower costs because they are more readily processed than metal alloys.
Previous procedures for the preparation of polypyrazoles involved formation of the pyrazole ring in the polymerization step. Difficulties in forming the pyrazole ring resulted in low viscosities or molecular weight. The polymers also had poor solubility characteristics and were not processable. The incorporation of a pyrazole rings as a part of a monomer would alleviate the problem of having to form the ring in the polymerization step. These polymers show excellent thermal stability and mechanical properties.
