The present compatibilization strategy involves the compatibilization of PTT with the second immiscible
phase, EPDM, by the introduction of a compatibilizer precursor (EPM-g-MA), which is physically miscible with the second phase (EPDM) but has chemical functionality (maleic anhydride group) which can react with the hydroxyl end group of PTT to form a graft copolymer at the interface as shown in reaction Scheme 1.
The role of a compatibilizer in a polymer alloy or blend is to improve interfacial adhesion between two immiscible
polymers resulting in formation of miscible blends.
Most polymer pairs, however, are immiscible
because of their high molecular weight and unfavorable interactions.
Preparation of MFC includes three technical steps: (1) mixing step, melt blending of two immiscible
polymers having different melting temperatures ([T.
During the past 4 decades, a very large number of papers have been reported on the morphology of immiscible
polymer blends as functions of blend composition and processing conditions (e.
These include interface capturing of immiscible
and diffused interfaces, Scale-resolved turbulence, Mass transfer rate (cavitation and vaporisation) and real-fluid thermodynamics addressing the compressibility effects for the liquid-vapour-air mixture.
They cover the Hele-Shaw problem, a joint motion of two immiscible
viscous fluids, mathematical models of in-situ leaching, and the dynamics of cracks in rocks.
Since most of the polymers are immiscible
, the combinations of immiscible
polymers involve chemical reactions and physical influences .
Though oil and water are immiscible
, most porous, spongy materials readily absorb both oil and water, making non-selective absorbent materials uneconomical for oil cleanups.
With ASE, normally immiscible
hexane and methanol injected into extraction cells separately were able to nearly duplicate extractions of chloroform and methanol, providing an option for replacing chlorinated hydrocarbon solvents.
2] can be injected in an immiscible
or near-miscible process at reservoir conditions.
Conversely, in partially miscible or immiscible
blends, the noncrystallizable polymer generally disturbs spherulite growth.
