AB  - The characterization of textured yarn is of great significance for both producers and final users. The influence of the texturing parameters (draw ratio and heater temperature) on the characteristics of the textured polyamide yarn has been investigated in this study. Textured yarn was charc- acterized by the degree of orientation, degree of crystallinity, breaking characteristics, shrinkage, elasticity characteristics, the contents of the end groups and degree of whiteness. It was observed that the mentioned characteristics changed as a function of time. The influence of yarn ageing on its characteristics was assessed. The parameters of polyamide textured yarn structure were determined by DSC.

AB  - Different polyimide resins were synthesized using 1,6-bis-maleimidohexane and the following compounds with terminal amino groups: 4,4-diaminodiphenylmethane, 4,4-diaminodiphenylsulphone, 1,4-bis-(3-aminopropyl)-piperazine and 4,4NN-bismaleimidodiphenylsulphone and 1,2-diaminoehtane and 1,4-bis-(3-aminopropyl)-piperazine. The thermal and thermooxidative behaviour of the polyimide resins was studied by thermogravimetric measurements (TG) in oxygen and nitrogen. Polyimide resins have been irradiated and their radiation stability evaluated on the basis of thermal and thermooxidative behaviour of irradiated samples. (C) 2003 Elsevier Ltd. All rights reserved.

AB  - The syntheses of 1,2-ethane-bis-maleamidoacid, N,N-1,2-bis-maleimidoethane (BME), and polyimide resins based on BME and four different diamines are given. The thermal and thermooxidative stability of the resins was studied by thermogravimetry (TG) following parameters such as temperatures for defined weight loss and initial decomposition rate, i.e. shape of TG and first derivative TG curves. Samples have been irradiated and their radiation stability evaluated on the basis of the thermal and thermooxidative behavior of the irradiated samples. The thermal behaviors have been analyzed and the resin based on the diamine with the benzene ring showed the best thermal stability. Radiation in the applied dose range showed an increase of thermal stability. (C) 2000 Elsevier Science Ltd. All rights reserved.
