A molecular theory is developed to describe quantitatively the permanent set taking place in
thin samples of vulcanized natural and synthetic rubbers held at constant extension at …

The residual extension which remains after a sample of rubber has been stretched for some
period, then released and allowed to recover, is popularly called permanent set. This set …

An important property of vulcanized rubber is an increase in the unstrained length after
stretching, the so-called permanent set. When stretching is for short duration at ordinary …

The investigation was undertaken in an attempt to establish the fundamental connections
between the physical properties of a typical vulcanized rubberlike polymer and its chemical …

Improvement in methods of characterizing the stress‐strain properties of vulcanized rubber
and of determining its molecular weight prior to vulcanization are described. Experimental …

Tensile strengths of natural rubber samples quantitatively crosslinked with decamethylene
dis‐methyl azodicarboxylate have been determined. The proportion of the azo vulcanizing …

The rigidity of rubber, considered as a network of flexible molecules with Gaussian
configuration functions, can be calculated for a particular sample if one is given a complete …

In considering existing information on the mechanical properties of raw rubber, it is not
generally possible to distinguish between the effects of elastic and of plastic deformation. In …

A natural rubber (NR) gum mix with a conventional N-cyclohexyl-2-
benzothiazylsulphenamide (CBS) accelerated sulphur system (0.5: 2.5 CBS/S) was …

A treatment is given of the effect of network flaws due to the finite chain length of the primary
elastomer molecules on the elastic properties of rubber vulcanizates. In this treatment full …
