Název v původním jazyce

Influence of the temperature applied during annealing/stretching on a structure of polypropylene film

Popis výsledku v původním jazyce

This istudy is focused on the influence of the temperature applied during annealing/stretching of bi-axially oriented polypropylene films using Fourier transform infrared spectroscopy (FTIR) method. There are several changes in a structural orientation of polypropylene after exceeding the temperature over glass transition point. The given mentioned changes include the reorganization of polymeric macromolecules in time and decreased defect concentration. Crystallinity degree of polypropylene is changed as a result of these processes and the evaluation and analysis was based on deconvolution infrared absorption spectra registred in transmission setup of FTIR-8601PC spectrometer at the room temperature of 23°C. It was proven experimentally that there is an increase in crystalline to amorphous phase ratio in a temperature range of 120°C - 170 °C with rising temperature of annealing/stretching of bi-axially orineted polypropylene film.
