Oxygen scavengers which are based on oxidation of iron powder dispersed in a polymer matrix are established in the packaging industry. They protect foods from oxygen. The iron particles have a diameter of several micrometers, which is too high to allow thin layers in multilayer film structures. A promising alternative is a developed nanoscale oxygen scavenger which is subject of this study. The aim...
Vinyl groups, i.e. 1,2-units of polybutadiene in the presence of various ruthenium complexes at elevated temperatures undergo an effective reaction of dehydrogenative coupling with vinyltrisubstituted silanes to yield silyl substituted units. This is a new type of functionalization of unsaturated polymers. The reaction products are identified by 1 H and 13 C n.m.r. and FTi.r...
