摘要

Thermogravimetric analysis data of about 500aliphatic,alicyclic and aromatic ('phenylene-R-') polymers,and numerous literature data,have been used to correlate polymer structure with thermal stability. The temperature of the extrapolated onset of the first major breakdown step has been used as criterion for thermal stability. The results,by polymer classes,are listed in the discussion section. The maximum stabilities obtained for various polymers and moieties,order of stabilities of linking groups,the effect of lengths of alkylene chains, tacticity,packing,branching,crosslinking, sidegroups and other factors have been discussed.
