Composition for increasing the yield of pulp, reduce the extractives and reduce the accumulation of material in a chemical pulping process.

摘要

Compositions and processes to increase yield of pulp, reduce the extractives and reduce the accumulation of deposits in a chemical pulping process.In general, this disclosure is directed to compositions and processes to increase the yield of the pulp.Reduce the extractives and reduce the accumulation of material in a chemical pulping process.In one method in particular, for example, this disclosure is directed to a composition comprising a surface active agent, an alkali mixture, at least one polymer.The polymer having a main chain segment linear which has two ends, at least one component of phosphorus.The phosphorous compound chemically bonded along the segment linear main chain of polymer and at least one component terminal.The component terminal chemically bonded to one or both ends of the segment linear main chain of the polymer.
