Chain Extension and Flexibility

The problem of high transition temperatures in rigid, strictly linear macro-molecules is also difficult to overcome. The obvious solution to find a solvent 

In this next sections an attempt will be made to collect on the examples of poly(p-phenylenebenzobisthiazole), poly-p-oxybenzoate and poly(p-ptenylene ter-ephthalamide) the sparse evidence suggesting that dynamic disorder may sometimes also be of importance for the understanding of stiff molecules.
