Intermolecular interactions in poly(vinylidene fluoride) and ε- caprolactam mixtures
Mixtures of poly(vinylidene fluoride) (PVDF) and ε−caprolactam (CPL) have been investigated as models for possible cross-interactions between vinylidene fluoride and amide structural units, that might account for the very fine phase morphology previously observed in PVDF/polyamide 6 blends. Over the entire composition range, the PVDF/CPL mixtures are monophase above the PVDF melting temperature...
متن کاملPotential Migration of ε-Caprolactam to Water and Wine as Affected by Transportation and Storage
Under normal sealing and storage conditions, Nylon-6, poly-caprolactam-based plastic laminates may release impurities to packaged foods and liquids and the application of heat for cooking often increases the rate of migration. Epsiloncaprolactam is one of the main contaminates found to migrate from a Nylon-6 polycaprolactam plastic film. The objectives of this study were to determine the effect...
متن کاملSynthesis of Polyamide 6 by Anionic Polymerization of ε-Caprolactam in an Internal Mixer: Effect of Polymerization Reaction Time
The main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. The reaction time and the rheological properties of samples during the polymerization were studied. The samples were characterized by Thermo Gravimetry Analysis (TGA), Differential Scanning Calorimeter (DSC) and FT-IR spectrometer. The melt flow behavior and ...
متن کاملP(iii)-cyclic oligomers via catalytic hydrophosphination.
A bulky secondary phosphine with an alkynyl substituent was prepared and shown to undergo catalytic hydrophosphination to give cyclic oligomers.
متن کاملSelf-assembled cyclic boron-dipyrrin oligomers.
Self-assembled cyclic boron-dipyrrin oligomers 3-5 obtained by the reaction of catecholyldipyrrin with boron trichloride were characterized by 1H NMR, MALDI-TOF MS, and X-ray measurements and the interaction between 3 and alkali metal ions was examined.
