Abstract
|
The objective of this work was to investigate the influence of irradiation conditions on grafting of styrene into tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride (THV) terpolymer films. Stressstrain measurements, infrared spectroscopy and electron paramagnetic resonance spectroscopy have been used to characterize the pre-irradiated polymer films regarding tensile strength, elongation at break, changes in the chemical structure and concentration of trapped radicals, respectively. Main-chain scissions associated with the formation of carbonyl end groups and end-chain double bond structures have been identified to be the reason for a moderate deterioration of the mechanical properties of the pre-irradiated films. The yield of grafting has been found to be influenced by THV grade, irradiation temperature and concentration of cross-linker.
