Full characterization of Polymers by Preparative Fractionation

Oct 11 2018 Read 362 Times

PREP mc2 is a preparative instrument intended for fractionating polymers by either chemical composition (TREF or CRYSTAF) or by molar mass. Samples are put into the vessels and the fractionation is performed automatically according to the selected method conditions in less than 24 hours.

Molar Mass fractionation is based on the solvent interaction with the polymer chains through a solvent/non-solvent combination. Polydispersity of the resulting fractions can be very narrow.

Composition fractionation is based on the differences in crystallizability of the copolymer resins and can be performed by dissolution (TREF) or by precipitation (CRYSTAF) approaches. A single solvent is used to separate fractions according to their composition by dissolution or crystallization at different temperatures.

Up to 16 fractions can be obtained from a single sample fractionation as per the sample collector capacity. Two different samples can be fractionated at the same time, in which case up to 8 fractions per sample can be collected per run.

This instrument facilitates the cross-fractionation studies, which have been shown to be a needed tool to fully characterize resins. Fractions collected can be analyzed by other techniques such as NMR, FTIR and DSC.
