Crystallization of Poly(ε-caprolactone) in Poly(vinylidene fluoride)/Poly(ε-caprolactone) Blend

Crystallization of Poly(ε-caprolactone) in Poly(vinylidene fluoride)/Poly(ε-caprolactone) Blend

The crystallization behavior of poly(ε-caprolactone) (PCL) in a poly(vinylidene fluoride) (PVDF)/PCL blend as well as on a highly orientated PVDF substrate was studied by means of POM, DSC and TEM. The results show that the miscibility of the PVDF/PCL blend and the spherulitic morphology of PVDF varies with the blend ratio. For all the compositions, the pre-existing PVDF crystals accelerated th...

Morphology & Properties of Blends of Starch –caprolactone Blend

A binary blend of polycaprolactone and starch in 70:30 weight ratio (known under the tradename “Envar”) was blended in various weight ratios with organosolv lignin (L) and organosolv lignin butyrate (LB) by solvent casting and melt blending. The thermal transitions observed by DSC revealed behavior resembling that of native polycaprolactone (PCL). Depression in melting temperatures obtained by ...

Photodegradation of Poly ( caprolactone ) / Poly ( vinyl chloride ) Blend

The photodegradation of a 1:1 blend of poly (caprolactone) and poly(vinyl chloride) has been studied by following carbon dioxide emission during UV exposure. Similar measurements were made on poly(caprolactone) and poly(vinyl chloride) homopolymers prepared and irradiated in the same way. It was found that the blend gave lower CO2 emission than either of the two homopolymers, indicating that th...

Biological Properties of Blend Nanofibrous Scaffolds from Poly(caprolactone)-Chitosan-Poly(vinyl alcohol)

(S)-6-Methyl-∊-caprolactone

The chiral title compound, C(7)H(12)O(2), a lactone derivative, features a seven-membered ring that adopts a chair conformation. The crystal structure is stabilized by weak C-H⋯O inter-actions occurring in the (100) plane. The absolute configuration was assigned on the basis of the enantioselective synthesis.
