Phase volume ratios yielded a critical polymer concentration of 1.87 wt.% HC (displaced considerably out of the minimum of the demixing curve towards higher polymer concentrations) and a lower critical solution temperature of 47°C.
Here, we report on a simple and versatile method of in situ polymerization of macrocyclic carbonates in the presence of a maleic anhydride polypropylene (mPP) matrix and a surface-active compatibilizer (i.e. PC grafted onto a mPP backbone generated in situ) to yield a micro- and nanostructured polymer blends consisting of a polycarbonate (PC) minor phase, and a polypropylene (PP) major phase.
The optimal calculated parameters were found to be concentration of Moringa gum-1% (w/v), N-vinyl-2-pyrrolidone-2% (w/v), and ammonium persulfate 10 mMol/L, which yielded a graft co-polymer of% grafting efficiency (24.23%).
Analysis of the rate and of the MWDs of the polymer formed yielded an estimation of the rate coefficient for transfer of the radical activity from the propagating VneoD radical to toluene and to polyisoprene.
The persistence length, which measures the apparent flexibility of a polymer against entropic force, yields an average of 0.37 ± 0.23 nm.
The 1/1 BAIL/12-hydroxydodecanoic acid molar ratio was found to yield polymers of the highest molar mass.
However, biophysical [ 4, 6, 16– 20] and crystallographic [ 21, 22] studies have provided evidence that these approaches yield polymers of markedly different structural character.
A model is proposed for the description of the viscoelastic and yield behaviour of polymer fibres.
The reaction under ethylene atmosphere produces alternating copolymer of the two monomers to yield the polymers composed of the C4 repeating unit with a 1,1-cyclopropanediyl group.
In one study, the thickness of interphase was assumed as a characteristic length scale and the main effects of interphase on stiffness and yield stress of polymer nanocomposites were evaluated [19].
