|
 | An experimental characterization and processing study of redissolved Kevlar and poly(p-phenylene terephthalamide)/sulfuric acid solutions is reported. Polarized light microscopy studies show the development of an anisotropic phase. When two phases coexist, negatively birefringent spherulites are observed. At higher concentrations, a single phase of coalescing spherulites is seen and following melting and subsequent cooling, nematic (threadlike) structures are observed. Viscosity and normal stresses were measured at various concentrations and temperatures. A ... |

| The development of high levels of chain orientation and tensile strength in fibers obtained from the wet spinning of liquid crystalline aromatic polyamide solutions has gained increased attention in recent years. Various other synthetic polymer systems have been found to exhibit liquid crystalline behavior including polypeptides, certain polyester copolymers, some vinyl polymers and p-linked aromatic polyamide-hydrazides. Various biological polymers such as RNA and DNA have been so identified as well ... |

| Authors:
Daniel D. Harwood; John F. Fellers; TENNESSEE UNIV KNOXVILLE
|
| The dilute solution viscometric behavior of poly(m-phenylene isophthalamide) dissolved in LiCl/dimethylacetamide was studied. Important aspects of this investigation included interactions between dimethylacetamide and LiCl, polymer-polymer association, and the capability of poly(m-phenylene isophthalamide) to become a polyion when dissolved in LiCl/Dimethylacetamide. Counterion interaction with the polyion and the ability to control the ion concentration gave rise to interesting variations in the hydrodynamic volume of poly(m-phenylene isophthalamide) leading to a maximum in ... |

|
| Of numerous ecosystem stability considerations, none probably affects ecosystem structure as drastically as the extinction of a biological species. As demonstrated by public concern about projects such as the TVA Tellico Dam Project where the persistence of the snail darter Percina tanasi is vascillating, extinction of a biotic component of a food chain is topical as well as ecologically fundamental. Viewing the importance of persistence-extinction phenomena, it is somewhat surprising ... |

|
| Authors:
J. F. Feller; B. F. Kee; TENNESSEE UNIV KNOXVILLE
|
| This paper reports a new phenomenological observation regarding the stress crazing of glassy polystyrene. It was found that the applied stress to initiate a craze, often called the critical crazing stress, is independent of molecular weight. Further, the gross structure of the craze does depend on molecular weight, and other phenomenological aspects previously reported have been reaffirmed. These observations are interpreted in the light of knowledge from the literature and ... |

| Investigations of the morphological structure of moldings of several polymers reveal that most have a composite structure. Studies on test specimens show that mechanical properties may be dependent on the amount and distribution of the various structural types within the sample. Application of this relationship for practical purposes is discussed using three examples drawn from the development of optimum molding practice for acetal resin. The optical microscope may be used ... |

| Studies of orientation in injection moldings have concentrated on the morphology of the specimen, that is the organization and orientation of folded- chain lamellae, since much better correlation with physical properties is found at this morphological level than at the level treating overall orientation of chain segments within the crystalline units. Published data on the morphology of injection moldings of polypropylene and polyoxymethylene are reviewed in terms of the concept ... |

| Authors:
J. Autain; TENNESSEE UNIV KNOXVILLE
|
| In a discussion on the toxicology of phthalate esters, it is concluded that the accumulated published information on these compounds indicates a low order of acute and chronic toxicity. Limited animal studies on several of the esters show that at relatively moderate to high doses, the esters can act as teratogenic and mutagenic agents. The esters also have demonstrated in tissue culture toxic effects at the cellular level. Although there ... |

| Authors:
E. S. Clark; TENNESSEE UNIV KNOXVILLE
|
| The development of morphology during injection molding of acetal homopolymer can be understood in terms of the interrelationships between melt rheology, crystallization kinetics, and thermal environ-ment. Three types of morphology occur: a skin of high molecular orientation, a less highly oriented intermediate 'transcrystalline layer', and a spherulitic core. The skin represents that portion of the melt crystallizing during the filling period. The variation in skin thickness in a molding is ... |

| A critical review of the literature on experimental and theoretical studies of the flow of polymer melts into and through dies is given. The development of vortex flow patterns in the die entry region with increasing flow rate is described and interpreted. It is suggested that these are caused by the stress field exerted by the fluids because of their viscoelastic character. The nature of distorted extrudates of polymer melts ... |

| While formulating the optimum trajectory one must at the same time synthesize some form of corrective control action along the way. Economic considerations also dictate that this control scheme be as simple as possible commensurate with the desired system accuracy. One approach to such a requirement is to design a linear controller that attempts to keep deviations of some or all the state variables from a standard trajectory small. 'Directional ... |
