Abstract
When polyethylene chains are stretched
the chains are regarded as being confined in an infinite cylinder withdecreasing diameter. The conformational properties of polyethylene chains confined in an infinite cylinder are investigatedby using rotational isomeric state model. Using the average conformational energy and entropy and the average length
wecan determine the elastic force f or the fraction of the energy term to the total forcefe/f
where fe=?/?and f=?/?.Comparisons with experimental data are also made.The results of these microscopic calculations are discussed in therms of the macroscopic phenomena of rubber elasticity.
