Abstract

1488932 Sulphofluorinating and oxidizing polymeric articles AIR PRODUCTS & CHEMICALS Inc 16 Jan 1975 [17 Jan 1974 (2) 19 Feb 1974] 49512/76 Divided out of 1488931 Addition to 1395949 Headings C3P and C3R [Also in Division B5] Shaped articles, particularly fibres, made of synthetic polymer material are treated with a gaseous mixture comprising 0À1 to 20% by volume of fluorine, 0À1 to 50% by volume of sulphur dioxide and no more than 21% by volume of oxygen. Preferably an inert carrier gas such as nitrogen is present. The treatment is for an hour or less. Sulphuryl fluoride-which is present in the reaction mixture-may be used instead of SO 2 with the same effects. Polymers treated in the examples are nylon 6, nylon 6,6, polyester, polypropylene, polyethylene, polyurethane and "Acrylan" (Registered Trade Mark). It is believed that the treatment results in some chain scission with carboxylate formation and the incorporation of -SO 2 F groups. Examples 13 and 14 disclose the treatment of polyethylene film.
