It is therefore useful to investigate the performance of existing thermodynamic models for complex polymer solutions which have not yet been widely studied. The present work studies the application of several activity coefficient models [P.J. Flory, Principles of Polymer Chemistry, Cornell University Press, New York, NY, 1953; T. Oishi, J.M.

The evaluation of these modelswas carried out both at infinite dilution and at finite concentrations and the resultscompared to experimental data. Furthermore, liquid–liquid equilibrium predictions for binary polymer solutions using six activity coefficient models are compared in thiswork. The parameterswere estimated for all the models to achieve the best possible representation of the reported experimental equilibrium behaviorSubmitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-06-14T18:49:36Z No. of bitstreams: 1 __ac.els-cdn.com_S037838...6d896eb219ce82168a6c37b52d3e3.pdf: 329745 bytes, checksum: 10f6ac69c56f8e2f0e3a5f4166468b64 (MD5)Made available in DSpace on 2012-06-14T18:49:36Z (GMT).
