- Abstract
- The morphologies, crystalline structures, and thermal and rheological behaviors of isotactic polypropylene (iPP) blended with dicyclopentadiene based hydrogenated hydrocarbon resin (HCR) were investigated using scanning electron microscopy (SEM), wide-angle X-ray diffractometry, and differential scanning calorimetry in detail. Furthermore, the transparency, mechanical properties, and water vapor and oxygen permeability of biaxially oriented polypropylene films, fabricated from these iPP/HCR blends using a biaxial drawing machine, were examined. It was found that crystallinity varies with the HCR content of the iPP/HCR blend. In addition, amorphous HCR with its high glass transition temperature (T-g) upon blending with iPP's amorphous structure affords improvements in various film properties, such as mechanical properties, transparency, and gas permeabilities.
