Thermally induced reorganization in LCP fibers

Molecular origin of mechanical strength

Journal of Thermal Analysis and Calorimetry

Abstract  

The molecular reorganization occurring in liquid crystalline polymer fiber during heat treatment is of great interest for many commercial reasons. Using thermal analysis techniques, WAXS and real time temperature dependent synchrotron SAXS, the structure and morphology of commercial LCP (liquid crystalline polymer), Vectran®, HBA/HNA (p-hydroxybenzoic acid/6-hydroxy-2-naphthoic acid), and its variant polymer fiber COTBP, HBA/HNA/BP/TA (BP-benzophenone, TA-terephthalic acid), have been examined. Both fibers have the typical liquid crystalline polymer structure, i.e., highly aligned with aperiodic sequencing along the fiber axis. There is a three-fold increase in strength in both fibers with heat treatment; however, the modulus is observed to increase significantly in COTBP but not in Vectran®. This paper reports on the changes and the differences on the structural and morphological behavior for both the as-spun and heat-treated LCP fibers. We propose an ‘oriented entanglement’ model to describe the differences between the two polymer fibers.

The process of structural reorganization and thermal history recurrence in Nylon 1010 were studied by using DSC through different heat treatments. The characteristics of both endothermic and exothermic peaks on DSC curve is explained reasonably. The viewpoint is advanced that crystallites assembly is characterized by premelting crystallisation peak. The temperature range sensitive to the crystal perfection is determined. The results provide theoretical basis for the processing and application of Nylon 1010.

A fizetésképtelen helyzetek kezelésével összefüggo eljárások alapvetoen reorganizációs vagy likvidációs típusúak lehetnek. Az elobbi célja, hogy az adós a hitelezoivel való megegyezés segítségével a muködését újjászervezve talpon maradhasson, míg az utóbbi alapvetoen a vagyon értékesítésén, illetve a követelések behajtásán keresztül a befolyó vagyon hitelezok közötti szétosztásával jár. Az egyes eljárási típusok konkrét megjelenési formája – az adott országban uralkodó gazdaságpolitikai célrendszer és beavatkozási szint szerint – rendkívül sokféle képet mutathat. A legkülönfélébbek lehetnek továbbá az eljárások közötti átjárhatósági viszonyok, egyszóval az eljárások kapcsolódási módjai.A reorganizációs és a likvidációs típusú eljárások kapcsolódásai együttesen eljárási rendszert alakítanak ki, mely eljárási rendszerek tipizálhatóak. Miután a jelenlegi gazdasági viszonyok között mind nagyobb hangsúly helyezodik a visszafordítható válság stádiumában álló cégek megmentésére, a cikk – a játékelméletbol ismert fogoly-dilemma játék segítségével – választ ad arra kérdésre, hogy vajon mindegyik tipizált eljárási rendszer ugyanolyan módon képes támogatni a reorganizációs célkituzéseket.

Abstract  

Although reorganization in metastable polymeric crystals has been recognized for over 30 years, the effect of molecular weight on the reorganization process has not been widely investigated. In this work three polymeric systems were studied: poly(vinylidene fluoride), polyamide 12, and poly(p-phenylene sulfide). For the polymers investigated, the lowest molecular weight sample was found to reorganize the most and, conversely, the highest molecular weight sample was found to reorganize the least. Comparisons of each system show that independent of molecular weight the reorganization rates among the three systems could be differentiated with the polyamide showing the greatest reorganization and the poly(phenylene sulfide) the least. Both conventional differential scanning calorimetry (DSC) and temperature-modulated DSC (TMDSC) were used in this study to investigate the reorganization process.

Abstract  

Polypropylenes of differing morphologies were examined by differential thermal analysis. The problems of reordering during the programmed heating are discussed. Four potential procedures by which the reordering could be inhibited are considered, and three of these are experimentally assessed. Their advantages and deficiencies are identified. Two pretreatments, an etching and a crosslinking, are recognised as able to qualitatively characterise the initial morphology, with a preference for the former. A test to identify the occurrence of reordering is identified.
