On the Orientation-Induced Crystallization of Polymers
In order to understand orientation-induced crystallization of polymers, we introduced an intermolecular interaction between polymer chains based on quantum mechanics. We therefore considered a pair of perfectly extended chains where the intermolecular interaction is assumed to be based on the hydrogen interaction with a single chain. When two protons of each extended chain become closer togethe...
متن کاملOrientation effect in the crystallization of polymer blend during extrusion
The processing during extrusion can be done either in the steady or transient state. In the first case, all components are added continuously in the extruder and the machine produces great quantities of mixed compound. In the transient state, the polymer that will form the matrix is fed continuously in the extruder and all other components are added as a single or multiple pulse. The mixed mate...
متن کاملCrystallization and orientation studies in polypropylene/single wall carbon nanotube composite
Crystallization behavior of melt-blended polypropylene (PP)/single wall carbon nanotube (SWNT) composites has been studied using optical microscopy and differential scanning calorimetry. Polypropylene containing 0.8 wt% SWNT exhibits faster crystallization rate as compared to pure polypropylene. PP/SWNT fibers have been spun using typical polypropylene melt spinning conditions. The PP crystalli...
متن کاملCrystallization Kinetics Study in Al87Ni10La3 Amorphous Alloy
In this study, the crystallization behavior of melt-spun Al87Ni10La3 amorphous phase was investigated by using X-ray diffraction and non-isothermal differential thermal analysis techniques. The results demonstrated that the amorphous phase exhibited two-stage crystallization on heating, i.e., at first step the amorphous phase transforms into α-Al phase and at second step Al11La3 and Al3Ni inter...
متن کاملwillingness to communicate in the iranian context: language learning orientation and social support
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
