Abstract: A method is disclosed for preparing a porous structure of ultra high molecular weight polyethylene. A heterogeneous composite of the polyethylene and a particular hydrocarbon is heated to a temperature above the melting point of the hydrocarbon but below the melting point of the polyethylene. The composite is then shaped. After such shaping the temperature is then raised to a temperature above the melting point of the polyethylene and maintained until complete fusion of the polyethylene particles occurs. Thereafter the hydrocarbon is extracted from the cooled shaped structure.

Abstract: An improved method of pulp or pressure molding a multilayer container is disclosed wherein the inner layer consists of fused water dispersible polyolefin fibers whereas the outer layer consists of a mixture of cellulosic fibers bonded together by fused water dispersible polyolefin fibers. The containers are useful because the polyolefin layer is resistant to the passage of liquid such as lubricating oils and semi-solids such as greases while the mixed layer of cellulosic fibers and the polyolefin fiber supplies sufficient strength to permit the stacking of the containers when filled.
