Simple viscoelastic model for the stress relaxation of rubber vulcanizates

ABSTRACT SEVERAL theories for the description of the long-term transients of stress relaxation of rubber-like polymers have been put forward1 which require complex distribution functions of

relaxation and retardation times. Tobolsky and Aklonis1 have postulated that such a complex relaxation modulus arises from torsional vibrations and internal rotations of the chain molecules

as well as motions of the entangled rubbery networks. The difficulty inherent in all these theories is either that they fail to explain why the relaxation and retardation spectra do not drop

very rapidly or that they require very complex assumptions such as cooperative changes of configuration involving whole groups of polymer strands which become dominant at long intervals of
