Enhanced hydrolytic degradation of heterografted polyglycidols: phosphonoethylated monoester and polycaprolactone grafts.

abstract：:Two organosolv lignins from different origins, namely, almond shells and maritime pine, were modified by using a nanoclay and nanosilicate. Prior to modification, they were activated via glyoxalation to enhance the reactivity of the lignins and thus ease the introduction of the nanoparticles into their structure. The ...
