摘要： Paper having improved properties, particularly tear strength, is prepared from a furnish containing at least 90 weight % of cellulose fibers and up to 10 weight % of olefin polymer fibrils. The fibrils are prepared by a differential temperature process of the type described in U.S. Pat. No. 4,013,751, are refined in isopropanol, and are treated with an aqueous solution of polyvinyl alcohol to sorb at least 1.0 weight % of polyvinyl alcohol on the fibrils. The fibrils are prepared from an olefin polymer having a weight average molecular weight of at least one (1) million.
