The flow birefringence method has been used to investigate sulphuric acid solutions of the two series of polyhydroxyphenylbenzoxazoleterephthalamides differing as to the position of the phenyl ring ( para - or meta -) in the chain. On the basis of th

The effects of stress on the relaxation transitions in thermostable polymers orientated in various conditions have been investigated. An increase of stress was found to smooth out a number of transitions, or even caused them to disappear. Those trans

The flow-birefringence of a number of samples of polycyclohexanamide, polycaprolactam and copolymers of the two, in solution in sulphuric acid, has been investigated. Analysis of these measurements, using Kuhn's formula, gives the length of the stati
