"Fractionation of PVME - Comparison of Two Large Scale Fractionation Techniques"

Ind. Eng. Chem. Res. 2009, 48, 6943-6948.

Abstract: The efficiencies of two large-scale fractionation techniques namely continuous polymer fractionation (CPF) and continuous spin fractionation (CSF) are compared. To this end, we used a commercially available sample of poly(vinyl methyl ether). Both methods ire suitable to reduce the nonuniformity of the sample below 0.6. The results demonstrate that CSF has a better fractionation performance than the progenitor method, CPF. A further advantage is the three times higher throughput of CSF.
