Poly (p-dioxanone) has been widely used as suture materials for surgical operation. The present studied represent a well understanding of crystallization process in both isothermal and non-isothermal conditions.

This paper reports the various effects of acrylonitrile content of SAN on the crystalline morphologies of PCL/SAN blends in ultrathin films. Confocal Raman spectrometry results a quantitative SAN distribution within the PCL crystals at lower crystallization temperatures. At higher temperatures, SAN is completely absent due to the higher crystallographic order of the PCL crystals. A correlation between the SAN distribution with the bending morphology is made with the miscibility nature of the blends.

For a binary blend of polymeric materials with crystallizable/noncrystallizable components, the interaction, thermal conditions determine the inclusion or rejection of the noncrystallizable components that might be interlamellar, interfibrillar, and interspherulitic or at multiple locations. An advance application of Raman spectroscopy is described for the quantitative analysis for the distribution of noncrystalline poly(butadiene) component in poly(e-caprolactone)/poly(butadiene) binary blends. The distribution of noncrystallizable component and their morphological change is analyzed with compositions and crystallization temperatures.
