Upon the analysis of the work of previous aulhors, in this study, both rotational viscosimetry and oscillatory rheomeiry were selected for the rheological characterization of the viscosity evolution during cure of both epoxy systems.
Rotational viscosimetry and oscillatory rheometry were used in this study to analyze the resins behavior under different mass conditions.
Solution viscosimetry measurements on solubilized samples were carried out both on extruded chips and on samples tested in dynamic rheological measurements at two different times (3 and 13 min).
In fact, the molecular weight [M.sub.n] of PET extracted from the uncompatibilized blends prepared by setting 5 or 20 min as time of mixing, determined by viscosimetry in phenol/tetrachloroethane solution (26), resulted to be very similar 18,800 and 18,600, respectively.
The changes of the average molar mass [M.sub.w], [M.sub.n], [M.sub.z], and molar mass distributions during multistep uniaxial drawing of poly(ethylene terephthalate) (PET) to achieve ultimate mechanical properties have been studied in detail by means of size exclusion chromatography (SEC) with triple detection: concentration, viscosimetry, and light scattering, using HFIP as solvent.
The molar mass distributions (MMD's) of the PET samples were determined by using the method of size exclusion chromatography (SEC) with triple detection: concentration, viscosimetry, and light scattering.
GPC coupled with intrinsic viscosimetry and NMR have not been revealed as suitable techniques to detect small amounts of LCB.
However, in high shear viscosimetry (like extrusion capillary rheometry), the mechanically induced disentangling effect must be also considered.
Viscosimetry was measured using a Ubbelohde size 2 viscosimeter at a temperature of 30 [degrees] C to obtain [M.sub.v].
This extracted portion was characterized by viscosimetry and a [M.sub.v] of 2.7 x [10.sup.4] was found.
