Thermosetting Polymers,chemical cross-linking of the chains. The properties of such a system depend upon the structure of the main chains, the structure of the cross-links, and the number of the cross-links Hence, many variants are possible. As the cross-link density increases, so normally does the heat resistance, but th

Fluorine-Containing Polymers,ermal stability of polytetrafluoroethylene (PTFE), whose preparation was first reported in a patent dated 1941.. The thermal stability of PTFE has been attributed to the high carbon-fluorine bond strength (487 kJ/mole in CF. compared with 418 kJ/ mole for C-H bonds in CH.). and to the shielding effe

Polymers with Aromatic Rings in the Chain,it is arguably the simplest of the aromatic ring systems, its investigation has played an important part in the development of heat-resistant polymers. Commercial products based on polyphenylenes have appeared from time to time but have met with only limited success, due in the main to difficulties

,Phosphorus-Containing Polymers—The Phosphazenes,ame to be known as “inorganic rubber” because of the similarity of many of its mechanical properties to those of natural rubber. Thermal decomposition of the polymer did not commence until about 300°C, but rapid hydrolysis to inorganic salts in moist air precluded any practical applications. Much ef
