Thermoreversible gelation behavior of blend of poly(viny1idene fluoride) and poly(viny1idene fluoride-trifluoroethylene) in y-butyrolactone solution was studied. Sol-gel transition temperature increased with the increase of polymer concentration, but was independent of the blend ratio of two polymer
## Abstract The thermodynamic behaviour of poly(vinylidene fluoride) (PVF~2~)/poly(methyl acrylate) (PMA) blend gels in diethyl azelate (DEAZ) was studied by differential scanning calorimetry at three different blend compositions (__x__ (weight fraction of PVF~2~ in the blend) = 0.75, 0.5 and 0.25)
Poly(vinylidene fluoride) (PVdF) converts easily to thermally reversible gel at room temperature in aliphatic ketones or cyclic ketones such as 3-pentanone, 3hexanone, cyclohexanone, and g-butyrolactone, etc. Gelation of PVdF in these ketones took place through crystallization of polymers from solut
