Description

Bamboo cellulose pulp was irradiated in air by 60Co γ-rays. Effects of γ-ray irradiation on the molecular weight and its distribution of bamboo cellulose were investigated by viscosimetry and gel permeation chromatography. The G(s) value was estimated at 0.94 μmol·J-1. The results showed that molecular weight of irradiated bamboo cellulose decreased and the molecular weight distribution narrowed with increasing dose.
