Study of the melting and crystallization behaviour of poly(ethylene oxide)-poly(vinyl alcohol) blends

Study of the miscibility and crystallization behavior of poly(ethylene oxide)/poly(vinyl alcohol) blends

“…Also, a T g of 74°C for neat PVA was found from the DMA results. They were about the same as those reported in Quintana et al 9 Coincidently, the DMA results of neat PVA also showed another broad loss peak around Ϫ28°C that was near the glass-transition temperature of PEO. It was a subglass-relaxation peak of neat PVA.…”

“…PEO contains ether groups, which are expected to induce hydrogen bonds or polar interactions with the hydroxyl groups of PVA chains. Quintana et al 9 studied the PEO/PVA polymer blend. They found the melting-point depression and negative polymer-polymer interaction parameter , which are considered characteristics of a miscible blend.…”

Blends of polycarbonate and acrylic polymers: Crystallization of polycarbonate

“…7). This effect has been observed with other polymer pairs, 1,11,15,26,32,35,55 while nonlinear behavior has also been reported. 14,17,18,56 Even at very high concentrations of acrylic, PC is still able to crystallize.…”

Crystallization of PVDF in the PVDF/PMMA blends precipitated from their non-solvents: Special “orientation” behavior, morphology, and thermal properties

“…For these blends, miscibility [1][2][3][4], morphological structure [5][6][7], and crystallization behavior [3,4,[6][7][8][9] have been widely investigated. The miscibility is related to specific interactions between polymers by hydrogen bonds or polar forces [1], which can be reflected by the crystallization behavior of blends. Furthermore, the morphological structure is always determined by miscibility and crystallization in blend system.…”
