“…TMA and/or dynamic thermomechanical analysis (DTMA) were used to determine the mechanical properties of a wide variety of polymers. These investigations include applications to nylon 66 annealed in glycerol (246), polyethylene oxide) (384), poly (ethylene terephthalate) (59), thermal aging in poly(vinyl chloride) (297), polyisobutylene (179), polysulfide, polyarylate, polyurethane, and silicone rubber joint sealants (296), Goodrite 2508 and Penacolite R2170 (288), Esprene EPDM 502 rubber (266), fiber-resin composites (144), heatresistant polymers (200), impact-resistant polystyrene (260), acrylated bisphenol A diglycidyl ether resin (124), polyolefin-polystyrene blends (286), water-soluble, secondary and triacetate cellulose acetates (320), a number of poly (ether ester urethane) and poly (urea urethanes) (340), and linear iso-and terephthalate polyesters (259).…”

This paper presents the influence of glass fibres on crystallization kinetics and on matrix morphology for poly(ethy1ene terephthalate) (PET)/glass fibre composites. The following parameters are also considered: fusion-crystallization conditions, thermal stability and the addition of nucleating agents in the matrix (talc or sodium benzoate). It clearly appears that the influence of those additives on the crystallization of PET is predominant compared to the effect of stiffening fibres. Moreover, the application of shear stresses at the PET/glass fibre interface promotes the growth of a different crystalline superstructure. ZUSAMMENFASSUNG:Der EinfluD von Glasfasern auf die Kristallisationskinetik und die Matrixmorphologie von Composites aus Poly(ethylenterephtha1at) und Glasfasern wurde untersucht. Die Schmelz-und Kristallisationsbedingungen, die thermische Stabilitat und die Addition von Kristallisationskeimen (Talkum oder Natriumbenzoat) wurden ebenfalls berucksichtigt. Der EinfluD dieser Additive auf die Kristallisation uberwiegt den der Verstarkungsfasern. Daruber hinaus fordern Scherspannungen an der PET/Glasfaser-Grenzflache das Wachstum einer anderen kristallinen Uberstruktur.

Differential scanning calorimetry and thermomechanical analysis are used for examining the thermal behaviour of amorphous poly(ethy1ene terephthalate) films in the glass-transition range. By variation of the heating rate between 0,2 and 100 K . d n -' , it is possible to obtain either an exotherm associated with a shrinkage, or an endotherm, or both of these phenomena.It is found that very low heating rates not only give rise to a retardation mechanism but also to a molecular rearrangement.
