This work presents new results on using organoclay with an appropriate polymeric compatibilizer as rheology-modifying additives for extrusion foaming of a linear polypropylene (PP), which by itself does not display strain hardening in extensional flow of the melt. The uniaxial melt-extensional viscosity behavior of several nanocomposites prepared with varying ratio of bound maleic anhydride to ...

The present invention provides wood derivatives and composite materials prepared by first solvating a lignocellulosic material using an ionic liquid. The solvated lignocellulosic material can be derivatized to incorporate functional groups, particularly groups that facilitate later combination with polymer materials, including non-polymer polymers. The polymeric materials can be combined with t...
