“…The plasticized PMMA/PVC blends have been receipted much attention because they are promised materials for polymeric electrolyte application. Some studies have showed that the miscibility of PMMA/PVC blends depends on molecular weights and proportion of each component [8][9][10][11][12][13][14], Therefore, using of a compatibilizer can further improve properties of the PMMA/PVC blends. Recently, Li et al [11] have synthesized poly(methyl methacrylategraft -polyvinylchloride) (PMMA-g-PVC) for blending with PMMA in order to prepare dual-phase polymer electrolytes, in which PMMA grafted content was evaluated by proton nuclear resonance spectroscopy with the value of 6.1 weight percent (wt.%).…”

This study presents the qualitative and quantitative analyses of Fourier Transform Infrared (FTIR) spectra of poly(methyl methacrylate)/poly(vinyl chloride) blends (PMMA/PVC), as well as PVC-g-PMMA graft copolymers. Graft copolymerizations of methyl mathacrylate (MMA) onto PVC macromolecules were carried out mixture of cyclohexanone/N,N-dimethylformamide as solvents, dibenzoyl peroxide as initiator and nitrogen medium. FTIR spectra of PMMA/PVC blends showed that there were molecular interactions between C=O groups of PMMA and C-Cl groups of PVC. Assignments of infrared absorption bands for specific groups of PMMA/PVC blends have been contributed. Using regression method, linear calibration curve between PMMA mole content and peak areas of C=O groups in FTIR spectra of the blends has been found when C=O peak areas were multiplied by an appropriate factor. PMMA grafted content and total PMMA formed content in PVC-g-PMMA graft copolymers have been evaluated. The results showed that grafted PMMA content was increased since PVC was initiatly dechlorinated by NaOH solution. The grafted PMMA content and total formed PMMA content were 5.05 wt.% and 11.25 wt.% respectively when MMA monomers were grafted onto neat PVC and modified PVC molecules.

“…On the one hand, the miscibility of CPE-cg-HEA with PVC was better than that of CPE. The branched chain of PHEA, having a greater miscibility with PVC, [19][20][21][22] enhanced the affinity between the modifier and PVC and contributed to a higher toughness for the toughening blends. On the other hand, CPE-cg-HEA and CPE might have had different toughening mechanisms.…”

Blends of poly(vinyl chloride) (PVC) and chlorinated polyethylene‐chlorinating graft‐hydroxy ethyl acrylate copolymer (CPE‐cg‐HEA) were prepared. CPE‐cg‐HEA, as toughening modifier, is a graft copolymer with a backbone of chlorinated polyethylene (CPE) and branched chains of poly(2‐hydroxy ethyl acrylate) (PHEA). Compared with PVC/CPE, CPE‐cg‐HEA demonstrated better toughening effects on the blends in the tensile strength, elongation at break, and impact strength. Particularly, compared to PVC/CPE blends PVC/CPE‐cg‐HEA blends with 5 phr CPE‐cg‐HEA showed an increases in the tensile and notched impact strength by 17.9 and 30% respectively, compared to the PVC/CPE blends. Differential scanning calorimetry analysis indicated that the miscibility of PVC/CPE‐cg‐HEA was better than that of PVC/CPE. An analysis of morphological structure showed that the grafting component of PHEA onto CPE promoted amalgamation between the primary particles of PVC and CPE‐cg‐HEA. Further research suggested that the toughening mechanism of the PVC/CPE‐cg‐HEA blends was different from that of the PVC/CPE blends. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

Summary:The miscibility behavior and intermolecular interactions among Dextran (Dx) with different molecular weight and Polyvinylpyrrolidone (PVP) blends were studied as dilute aqueous solutions at 25 8C by viscosity method. The intrinsic viscosity and the interaction coefficient were experimentally measured for each polymer-water as well as for Dx-PVP-water systems. These results served for the prediction of miscibility of the Dx/PVP blends with various blend compositions by usingD h ½ m ,Db m ,Dk AB ,DB,m and a parameters. Except Dx4/PVP with its all compositions (Dx4 with nominal molecular weight of 110 000), other blend systems are found to be almost miscible. The density measurements of these polymer solutions and their blends were conducted in order to compare with the viscosity findings. Lastly, all Dx with different molecular weight, PVP and their blends were characterized by infrared spectroscopy (FT-IR), and differential scanning calorimetry (DSC).
