The effect of uniaxial orientational drawing and subsequent isometric annealing on the molecular mobility of poly(vinylidene fluoride) was studied by dielectric spectroscopy and dynamic mechanical analysis. The influence of orientation, the polymorph

The degree of transformation of polyethylene with chlorosulphonic acid depends on the number of branches. It is increased not only by using better swelling agents, but also—and prevailingly—by an increase in the amorphous portion of the starting

Doubly oriented polycaprolactam films were annealed with the ends free at temperatures between 145 and 200°C for 30 min. As the annealing temperature rose the long period increased, the transverse dimensions of fibrils grew anisotropically, and the

The effect of the annealing temperature on the structure of unoriented polyamide 6 was studied by swelling in methanol and small-angle X-ray scattering. The observed values of mean-square fluctuations of scattering density can be explained by using a

The kinetic theory of rubber elasticity has successfully explained the macroscopic mechanical behaviour of polymer networks starting from the thermodynamics of individual molecules [1]. This approach, however, cannot be applied to semicrystalline pol
