Solvent action in glycol ethers comes from the C O C ether linkage. In ketones, the double bond oxvgen does the work. Shell Chemical's Pent-Oxone is the only commercially available solvent with both these functional groups. are t a k e n after o n e h o u r o n a 5 0 / 5 0 s o l v e n t / t o l u e n e m i x t u r e w i t h t h e indicated Vinylite** resin: 10% VYNS-3

chloride/vinyl acetate copolymer solutions. It has a better odor than other vinyl solvents and is proving valuable in vinyl adhesives as well as acrylic lacquer thinners. In nitrocellulose lacquers, PentOxone retards blush, dries in reasonable time. It acts as a coupling agent in sludge removing compounds.
