 | A limited reversible loss of physical properties with increasing moisture content has been demonstrated in the EPON 828/1031 resin. Permeability measurements have been made on resin and laminate. Serious damage to laminates with the application of high pressure water to exposed filaments has been demonstrated. (Author) |

| The objective of the investigation is the development of new thermoplastic and thermosetting resins from phosphonitrilic chloride trimer for high temperature electrical applications. Polymers were prepared by linking together bifunctional phenyl-and phenoxysubstituted trimeric phosphonitriles. Linking groups include oxygen, nitrogen, hydroquinone, tetrahydroxyaromatics and groups derived from the reaction of phosphonitrile isocyanates with glycols or diamines. The oxygen-linked and hydroquinone-linked polymers appear most promising. New syntheses of phosphonitriles of reduced functionality are ... |

| Stress cycling of resin/fiberglass laminates at fiber stresses ranging from 13,000 to 70,000 psi does not significantly alter the physical properties of the laminate. At high fiber stress levels, laminates developed cracks parallel to the surface filaments. These cracks were observed after 10,000 cycles at fiber stresses in excess of 50,000 psi. (Author) |

| Improved spinning speeds up to 900 ft/min were reached. A larger diameter (.040 inch) spinneret, discounting presumably some of the melt fracture limitations experienced with the smaller diameter spinnerets, permitted higher thermal jacket temperatures to be used and as a result the higher spinning speeds. The evaluation of the low thermal hazard extrusion head remains incomplete and the desired increase in I. V. was not obtained. (Author) |

| The objective of the investigation is the development of a new thermoplastic and thermosetting resins from phosphonitrilic chloride trimer for high temperature electrical applications. Improved methods for introducing phenoxy blocking groups into the trimer were developed. Additional work was done on the amino derivatives. Copolymerization of phosphonitriles of reduced functionality with hydroquinone was studied, and the introduction of the isocyanate function into the trimer was accomplished. (Author) |

|
| This report was prepared in order to present the results of an analytical and experimental effort to provide extra high strength purchase tapes with improved wear and engaging speed characteristics for the BAK-9 arresting sys tem. The purchase tapes now used on the BAK-9 barrier have an ultimate strength of 70,000 pounds and are not capable of exploiting the full thermal energy potential of the absorber unit. Using the existing ... |

| Reviews of technical literature on diffusion theory, diffusion properties of gases (water vapor) in polymers, diffusion measurements, the effects of moisture on resins and resin/glass laminates and mechanisms of water absorption were carried out. Two methods for determining the diffusion constants for moisture in polymers have been adapted to the requirements of the project. The diffusion constants for a number of candidate materials have been measured and others are in ... |

| The objective of this investigation is the development of new thermoplastic and thermosetting resins from phosphonitrilic chloride trimer for high temperature electrical applications. A polymer from P3N3(Oc6H5)3.5(OC2H5) 1.25C11.25 was prepared and submitted to the New York Naval Shipyard for evaluation. Work was done on phenyl, phenoxy, and dimethylamino blocked monomers, and on the copolymerization of phosphonitriles with hydroquinone. A tetrahydroxy benzene derivative was reacted with P3N3(C6H5)2C14. (Author) |

| The problem of delaying transition from laminar to turbulent flow has long been under investigation. This report presents a bibliography on the work that has been done for the last 40 to 50 years on this problem of transition, specifically for incompressible flow, over flat plates or in pipes. The articles included in this list are concerned with two questions: (1) What is the mechanism of transition, and (2) How ... |

| The objective of this investigation was the development of new thermoplastic and thermosetting resins from phosphonitrilic chloride trimer for high temperature electrical applications. Derivatives of phosphonitrilic chloride trimer were prepared with a portion of the chlorines replaced by thermally stable phenyl or phenoxy blocking groups, and the remaining positions occupied by reactive chloro, ethoxy, or dimethylamino groups. The derivatives or mixtures of derivatives containing phenoxy, ethoxy, and chloro groups in ... |

|
| This project was undertaken to develop new thermoplastic and thermosetting resins from phosphonitrilic chloride trimer for high temperature electrical applications. Derivatives of phosphonitrilic chloride trimer containing phenoxy, ethoxy, and chloro groups in various proportions have been found to polymerize to hard, clear resins by the elimination of ethyl chloride and the formation of P-O-P linkages. Further work on monomers for this polymerization is also described. (Author) |

| Aging studies and the effectiveness of antioxidants for elastomers are discussed. Cumene oxidation indicates antimony oxide and chlorinated paraffins protect materials by altering the path of oxidation. Ethylene propylene copolymer can be protected with Hypalon 40 and antimony sulfide; polyurethanes are not protected by Sb2O3 and chlorinated paraffins. Aging of protected polyethylene in a mild gamma field at 450 F in air causes severe degradation. Steam and water aging of ... |

| A carbon black-reinforced polyethylene containing 9 parts of Sb2O3 and 5 parts of polyvinyl chloride retained 92% of its room temperature tensile strength and 83% of its elongation after being aged 4 days at 450 F. in air. A carbon black-reinforced polyethylene containing 5 parts of both Sb2O3 and polyvinyl chloride and cured by electron irradiation retained 73% of its 450 F. tensile strength and 55% of its elongation after ... |
