A cut resistant fabric is made from woven or knitted yarn; the yarn includes a cut resistant fiber having a tenacity of less than about 10 grams/denier. A cut resistant fabric is made from woven or knitted yarn. The yarn includes a polyethylene fiber having a tenacity of less than about 10 grams/denier and a molecular weight of about 100,000. The yarn may be in the form of a composite yarn having a core and a wrap. The polyethylene fiber is in the wrap.

An extrusion blow molding process for a heat-treated, liquid crystalline polymer is provided. By the process, molten polymer having improved melt strength, is vertically extruded downward into space through a parison-forming, annular gap. Sag resistant parisons are formed. Beneficially, the parisons may be formed periodically. Advantageously, large-sized parts or structures may be produced.

Extrusion blow molding of thermotropic liquid crystalline polymers

An extrusion blow molding process for a filled, liquid crystalline polymer is provided. By the process, molten polymer having improved melt strength, is vertically extruded downward into space through a parison-forming, annular gap. Sag resistant parisons are formed. Beneficially, the parisons may be formed periodically. Advantageously, large-sized parts or structures may be produced.

Sintered polybenzimidazole articles are obtained by compacting a particulate, dried polybenzimidazole resin under a pressure of 2,000 to 10,000 psi in a mold, heating the formed article to a temperature in the range of 825.degree. to 950.degree. F. for at least four hours, cooling the polybenzimidazole article to below 800.degree. F. while maintaining the article under a pressure of 2,000 to 10,000 psi, and thereafter heating the constrained formed polybenzimidazole article to a temperature in the range of 825.degree. to 950.degree. F. for at least one hour.
