Abstract: ABSTRACT OF THE DISCLOSURE This invention discloses a new bubble forming and stabilizing device for use in a continuous extrusion process for making a blown film and a process for using same. The apparatus comprises a bowl shaped mandrel mounted subsequent to a die, the mandrel has an undersurface extending substantially parallel to and spaced from the path of travel of the blown film from the die and the undersurface is contoured to guide a stream of cooling air along its surface between the undersurface and the blown film as the blown film emerges from the die. The apparatus allows for increased production rates and improved physical properties of the forming bubble by creating more efficient heat transfer from the forming bubble to the cooling air stream. The device also provides support for the molten bubble during its most unstable state.

Abstract: ABSTRACT      Corrosion of metals in contact with an aqueous solution is reduced  by adding an effective amount of an oxygen scavenger selected from the group of phloroglucinol and other scavengers of the formula:    wherein R1, R2, and R3 may be the same or different and are each a member selected from the group consisting of hydrogen, and lower alkyl having 1 to about 8 carbon atoms; or water soluble salts thereof.
