The polymers are readily soluble in a variety of solvents such as N,N-dimethylformamide, NN-dimethylacetamide, dimethyl sulfoxide, N-methyl-2-pyrrolidinone, pyridine and m-cresol and can be cast to form flexible and tough films. The glass transition temperatures of polymers (T-g) are in the range of 301-327degreesC, and the temperatures for 5% weight loss in nitrogen are in the range of 498-521 degreesC.
