Abstract
  In this study, changes in optical behavior of Poplar Kraft lignin before and after methylation by using dimethyl sulphate, was monitored by measuring optical indices ( brightness,light absorbtion coefficient, light scattering coefficient,light absorbtion coefficient to light scattering coefficient ratio ...  Read More

Rabi Behroz; Hamed Unsi kord khelili; Saeid Kazemi najafi

Volume 26, Issue 3 , September 2011, , Pages 454-465

https://doi.org/10.22092/ijwpr.2011.117201

Abstract
  Effect of Kraft lignin as a compatibilizer on the short-term water absorption (2 and 24 hours) and mechanical properties of wood flour-polypropylene composites was studied. The black liquor of Chooka pulp and paper mill was acidified and Kraft lignin was extracted by precipitation.  The extracted ...  Read More
