Cyanoethylated of wood pulp was carried out at different conditions including acrylonitrile concentration, time, and temperature of the reaction. Some mechanical properties of paper sheets prepared from the cyanoethylated wood pulp were examined. Cyanoethylated paper sheets acquired higher breaking length, fold number, and burst factor than the untreated paper sheets irrespective of the conditions used for cyanoethylation. On the other hand, the tear factor of cyanoethylated paper sheets was generally lower than that of the untreated control through under certain conditions cyanoethylation brought about substantial improvement in tear factor. The water retention value and beating time are decreased depending upon the condition of cyanoethylation used.
