Transmission electron microscopy (TEM) of amorphous and semicrystalline isotactic polystyrene (iPS) thin films deformed well below T g, suggests the same crazing mechanism to operate in both cases. Therefore, by analogy with the amorphous case, highl

In thin amorphous polymer films, the entanglement density, ve, strongly influences the draw ratio during micronecking and the competition between cavitational and non-cavitational processes, often referred to as crazing and shear deformation respecti

The sub-T g relaxations of Bisphenol-A polycarbonate (BPA-PC) can be selectively altered by appropriate chemical modification. It is established that these secondary relaxations are responsible for the in-chain cooperative motions of BPA-PC and have

Step-strain ridges are known to form when glassy polymers are subjected to a stepwise series of strain increments. For relatively short times between increments (ageing times) and at relatively low temperatures, these step-strain ridges (studied here

Cross-links have been introduced into thin films of PES (polyethersulphone)/1 wt% sulphur by heating them in air at 350 °C. The effect of this is to suppress crazing in favour of shear deformation in high-temperature regimes where disentanglement cr

Recent work suggests that the origin of fibril breakdown is disentanglement of polymer chains in the ‘active zone’ at the craze-bulk interface, where the deformation ratio of the polymer is increasing towards that of the fully formed fibril, and

The crazing stress in glassy polymers is modeled as a function of temperature in terms of a block and tackle mechanism for disentanglement of polymer chains taking into account the possibility of effective molecular weight reduction in the regime of

In tensile tests of polyethersulfone it is found that, as the temperature is raised, samples of low molecular weight exhibit a ductile–brittle transition. Thus, this normally tough polymer becomes less so at evaluated temperatures. Ultimately as th
