Structure-Stability Relationships of Polymers Based on Thermogravimetric Analysis Data II. Polyheterocyclics.
Abstract
Thermogravimetric Analysis data of hundreds of aromatic-heterocyclic polymers, including AFML results as well as literature data, have been used to correlate 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. The maximum stabilities obtained for various polymers and moieties, the orders of stability of linking groups, the effect of o-, m-, p-substition, of crosslinking, molecular weight, side groups and other factors have been discussed. An attempt has also been made to correlate TGA data with isothermal aging data in air.
