“…The polymeric films can be also prepared by the mixing of hydroxypropyl cellulose with poly (vinyl methyl ether) [13]. Moreover, fluorinated allyl-vinyl ethers are being reported to be substrates for Claisen rearrangement reactions readily in temperatures below À30 8C [14][15][16][17][18].…”

“…A number of studies have been reported on the subject. The general regularities of complex formation reactions between poly(carboxylic acids) and proton-accepting non-ionic polymers with formation of interaction polymer complexation via hydrogen bonding are summarized in several reviews (Jiang, Xiang, & Zhou, 1999;Nurkeeva, Mun, & Khutoryanskiy, 2001;Nurkeeva, Tyukova, Suvorova, Mun, Dzhusupbekova, & Khutoryanskiy, 2005).…”

The miscibility behavior and physico-mechanical properties between methyl cellulose (MC) of different molecular weights (4 × 10(4) and 8.3 × 10(4)g/mol) and poly(acrylic acid) (PAA) were studied by viscometry, differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), tensile strength and scanning electron microscopy (SEM) using water as a solvent. Various formulations were designed to investigate the effects of process variables such as pH on the physico-mechanical and miscibility properties of MC/PAA blends. The rheological features for the obtained blends are strongly dependent on the molecular weight of the MC used and pH. The viscosity measurements showed that all blends have non-Newtonian shear thinning (pseudoplastic) behavior. These blends have a single glass transition indicating that these blends are able to form a miscible phase due to the formation of hydrogen bonds between the hydroxyl group of MC and the carboxyl group of PAA. The MC/PAA blends exhibit good mechanical properties, thermal stability, characteristics of a MC-PAA polymer network. SEM of the blends showed no phase separation, when compared with the pure MC and PAA.

“…Many experimental and theoretical methods, such as thermal analysis [1] , electron microscopy [2] , dynamic mechanical studies [3] , and viscometric techniques [4 -7] , are used to investigate polymer-polymer miscibility. Viscometric measurement is a good, effective, quick, and inexpensive method to determine polymer-polymer miscibility in solution.…”

Dilute solution viscometry method is used for studying viscosity behavior of newly prepared N , O -carboxymethyl chitosan (NOCC), cellulose acetate (CA), and their blends at different compositions (0/10, 2/8, 4/6, 5/5, 6/4, 8/2, 10/0). In this method, reduced viscosity ( η sp / c ) and inherent viscosity (ln η rel / c ) of the given polymer sample have been determined by measuring the fl ow time of the polymer sample in acetone solvent. Huggins ( k ) and Kraemer coeffi cients ( k ′ ) for given polymer-solvent system are calculated from the extrapolation of plots ( η sp / c ) versus ( c ) and (ln η rel / c ) versus ( c ). The miscibility of this polymer system is determined using different criteria such as ∆ b , ∆ b ′ , b 12 exp , interaction parameter ∆ [ η ], thermodynamic parameter α , and modifi ed thermodynamic parameter β . Based on the positive or negative sign of this criteria, miscibility of the polymer system is investigated. The results of the dilute solution viscometry method suggested that the NOCC/CA blends are miscible at the compositions range of 4/6, 5/5, 6/4, and 8/2 and completely immiscible at the 2/8 composition. The results are also supported by Fourier transform infrared analyses of all the compositions.
