- SUPER ABSORBENT POLYMER RECYCLING TO PRESSURE SENSITIVE ADHESIVES
-
Methods for upcycling crosslinked sodium polyacrylate to pressure sensitive adhesives via (a) mechanochemical chain-shortening and esterification or (b) esterifying with high conversion with a Fischer esterification process are disclosed. Also disclosed is a pressure sensitive adhesive prepared by the disclosed methods and articles comprising the pressure sensitive adhesive, including, but not limited to, pressure sensitive tape, a bandage, a label, note pads, a decal, a stamp, an envelope, a sticker, packaging, automobile trim, and a film.

- WAX COMPOSITION OF SARGASSUM FULVELLUM
-
Sixty-seven compounds were characterized in the wax of Sargassum fulvellum.Characteristic components were the 5-methylhexyl esters of octanoic, decanoic, lauric, myristic, palmitic, palmitoleic, stearic, oleic, linoleic and linolenic, and the 2-ethylhexyl esters of the same acids.The wax of S. fulvellum contains hydrocarbons (1.6percent), esters (21.8percent), free acids (74.9percent) and free alcohols (0.3percent).The principal free alcohols range in chain length only from C6 to C7. - Key Word Index: Sargassum fulvellum; Sargassaceae; Phaeophyta; wax; 5-methylhexyl esters; 2-ethylhexyl esters; 5-methylhexanol; 2-ethylhexanol.
