Parameter -y is geometric factor and is used to research the effecl of molecular architecture (linear and siar) and styrene content of SBS on the miscibility
Since the dynamic mechanical analysis has indicated that the degree of miscibility
is not affected by the bromination, the reason for the higher tensile strength of the NR/BEPDM is thought to be due to the migration of curatives from NR to the more polar BEPDM resulting in a much better co-curing of the NR/ BEPDM blend.
On the contrary, CPE25 addition initially decreased the transition point as compared with pure polymer but on average the behavior shifted to higher frequency values and the highest transition frequency of 3.4 rad/s was observed at 30% CPE content, which would have resulted because of better miscibility
of the phases.
For properties that are not affected by the polyurethane molecular weights, such as the glass transition temperature and phase miscibility
(as indicated by the peak position and peak width of the tan [sigma] curve), both elastomers are quite similar.
From which we could observe a good miscibility
of the two components, as the rubber particle size (about 1-2 pm) and the interface between the two phases remain unchanged regardless of the POE-g-MAH content.
These equation of state parameters were used in the Sanchez-Lacombe equation of state to predict blend miscibility
Not all polymers form stable films at the air/water interface; therefore, it is not easy to determine good pairs to compare the miscibility
in the bulk state with that in a film spread at the air/water interface.
of PHBHHx/PVPh blends was studied first with DSC.
Therefore, it is vital to know exactly which variables influence the miscibility
of polymers with amines.
Several material combinations cause issues because of a decreasing miscibility
during cooling and the formation of brittle phases.
In thermodynamics, miscibility
or solubility means mixing of two or more components on the molecular level, which results in a homogeneous structure with equal thermodynamic state variables.
of the two components, we calculated the ideal values of the molecular area ([A.sub.id]) of the mixed DPPC-CUR monolayers.
