Poly(butylene n-alkylenedionate)s (PBADs), which are polymers that potentially biodegradable in various environments, exhibit excellent thermal and mechanical properties similar to those of polyethylene because their long alkyl chains. However, although it has not yet been experimentally verified, is known differences the chain length affect biodegradability PBADs. In this study, we synthesized...
Unprotected wood exposed outdoors suffers from photodegradation due to absorption of UV light by lignin and dimensional changes because of moisture absorption or desorption by free hydroxyl groups in wood constituents. Chemical modification of cell wall polymers is one of the effective methods of inducing dimensional stability and UV resistance in wood. In this work, etherification of Scots pin...
The synthesis of two types of viologen dendrimers with peripheral carboxyl groups is described. Their interaction with plasmid DNA and CT-DNA and the influence of time evolution and electrolyte on dendriplex formation have been electrochemically investigated. A negative potential shift appearing in the cyclic voltammograms of the dendrimers indicates dendriplex formation on the time scale of 15...
