Poly(vinylidene fluoride)/poly(vinyl acetate) miscible blends: 1. Thermal analysis and spectroscopic (FTi.r.) characterization

Strengthening of poly(butylene adipate‐co‐terephthalate) by melt blending with a liquid crystalline polymer

“…[15][16][17][18][19] LCPs are known to have superior physical properties. Moreover, LCP can also deform into fine and elongated fibrils within an isotropic matrix under suitable processing conditions.…”

Miscibility and Crystallization Behavior of Poly(ethylene terephthalate)/Poly(vinylidene fluoride) Blends

“…[6] The miscibility arises due to the specific interactions of cCF 2 dipoles of PVF 2 chain with cC2O groups of the other polymer. [7,8] So far most of the known miscible binary polymer blends constitute either from two amorphous polymers or from one crystalline polymer and one amorphous component. [1 -4] In the study of crystalline polymer-crystalline polymer blends, the major emphasis has been given to the field of co-crystallization.…”

“…So in the blends of PVF 2 and PET there is a chance of specific interactions between cCF 2 dipoles of PVF 2 and cC2O groups of the ester. [7,8] Molecular modeling through MMX program [25,26] of a a-PVF 2 chain and a monomeric unit of PET indicates (Scheme 1) that the distance between carbonyl oxygen and cCF 2 dipole for the energy minimized structure is ca. 3.73 to 3.81 which is close to (within 3%) the van der Waals distance between the two groups (3.65 ).…”

Multifunctional Porous Poly(vinylidene fluoride)‐graft‐Poly(butyl methacrylate) with Good Li+ Ion Conductivity

“…The graft copolymers have peaks at 532, 613, and 794 cm À1 characterizing the formation of a-polymorph as in pure PVDF. [46,47] It is evident from the figure that the 529.1 cm À1 peak in PVDF (>CF 2 bending) has shifted to 532.2 cm À1 in the PB graft copolymers and also that the 759.9 cm À1 peak of PVDF (>CF 2 bending þ skeletal CFÀCHÀCF bending) [47] has shifted to 763.3 cm À1 . In the right-hand side of Figure 9, the subtracted >C¼O peak of PB graft copolymers from that of PnBMA are shown.…”

“…The nature of supramolecular interaction is expected to be dipolar through the >C¼O dipoles of PnBMA and >CF 2 dipoles of PVDF. [47] Mechanical Properties…”
