摘要
Melt-blown microfiber webs are prepared from polyarylene sulfide polymers, particularly polyphenylene sulfide. A small amount of a phosphite or phosphonite compound is added to the extruder feedstock. The additive essentially eliminates spurious polymer particle formation at the extruder die openings, even over sustained production periods. The polyarylene sulfide microfiber webs so produced are thus essentially free of spurious particulates, and the web defects which may be caused by such particulates.
