    摘要: The invention concerns an improved process for producing high performance polyolefin member. The process comprises the steps of preparing a solution comprising a polyolefin and a solvent, extruding or spinning the solution into an air gap to form a fluid member, cooling the fluid member to form a solvent-containing gel member, and removing at least partly the solvent from the gel member to form a solid member before, during and/or after drawing the member. Furthermore, the process involves the presence of an antifoaming agent comprising an aryl sulphonic acid or an alkyl naphtyl sulphonic acid. The invention further concerns the geltruded polyolefin member comprising aryl sulphonic acid or alkyl naphtyl sulphonic acid.
