The literature was reviewed and some interesting data relative to ozone attack was obtained. A sample of a new experimental neoprene latex was examined; the use of polyisoprene as a means of preventing the crystallization of Neoprene 673 was investigated; and the behavior of neoprene latex on prolonged, unagitated storage was determined. ASP-100 clay and Antox were both evaluated. The investigation of straining latex compounds thru felt was continued. Sample films for X-ray diffraction and electron microscope studies were submitted for test. Flight tests were conducted to correlate flight performance with laboratory findings and results were as generally expected. Balloons designed for flight in the Tropical and Arctic Zones performed extremely well well in the Temperate Zone. The failure of large Balloons to reach their theoretical altitudes is discussed, and a new approach to the problem of the very high altitude balloon is outlined with the initial compound development work undertaken.
