โœฆ Synopsis

The influence of the concentration on the behaviour of a soil fulvic acid is analyzed by conductimetric titrations. The values obtained (variation of molar conductivity between ca. 134 to 82 and variation of the degree of coverage between 0.31 to 0.16 when the concentration of fulvic acid rises from 20 to 100 mg 1-l) are explained by the counterion condensation theory and parameters derivated are calculated. The influence of small quantities of an organic solvent is also analyzed.

In food packaging applications where low-density polyethylene (LDPE) ยฎlm containing a-tocopherol is used, the antioxidant may have a dual function, i.e. to protect the polymer from oxidative degradation during processing, and to delay the onset of oxidation of the packaged foodstuff during storage.

Adsorption of polycation as well as the modification with oppositely charged polyelectrolytes is a useful tool for surface modification. As shown previously, a strong enhancement of the attainable specific cationic surface charge was observed, e.g., with poly(diallyl-dimethylammonium chloride) (PDAD
