Abstract: Addition of polysulphide (PS) during the pulping is investigated in the laboratory. Polysulphide was found to be advantageous to extend the cooking. The present study deals with polysulphide pulping of Populus deltoids Marsh The benefits gained were in terms of increased pulp yield without considerably affecting the quality of the pulp. The tear and burst values of the PS pulps were found to be slightly lower, while the tensile index values were found to be comparable with that of kraft pulp. The results demonstrate the better utilization of fibrous raw material for paper-making in terms of increased pulp yield and better physical and other strength properties of paper.
