ABSTRACT:
A stabilized synthetic polyolefin pulp-cellulose blend is prepared by adding 0.1-1.0% by weight of an antioxidant (a hindered phenolic and/or phosphite antioxidant) to a solution of a polyolefin and solvent wherein the antioxidant is homogenously dispersed therein, forming the polyolefin into a polyolefin pulp, and then mixing the polyolefin pulp with from about 55 to about 90% by weight of a wood pulp to produce the blend. This blend with improved higher ignition temperature is used in the absorbent products industry as an absorbent core, when the blend is heated sufficiently to melt the polyolefin.
