The Study of Thermolplastic Elastomer Based on Polyamide 6: Preparation, Morphology and Mechanical Performance

Abstract

In this study,a new thermoplastic elastomer based on polyamid 6, and polytetrahydrofuran was prepared by continuous hydrolytic ring-opening polymerization process. The effective of adipic acid content on the number-average molecular and the content of amino end groups was investigated. The morphology deduce of TPMP, mechanical performances were also investigated.

Structure and morphology of thermoplastic polyamide 6 elastomers with different soft segment content and their foaming behavior using supercriticalCO2

“…Thermoplastic polyamide elastomers (TPAEs) are a new member of the thermoplastic elastomer family, composed of rubber-phase polyester or polyether and plastic-phase polyamide (PA), including PA6, PA12, PA11, PA1012, and aromatic polyamide. [1][2][3][4][5][6][7] The physical cross-linking deriving from crystalline polyamide hard segments contributes to the superior strength and hardness of TPAEs, while the flexible polyester or polyether soft segments gave it excellent toughness. Therefore, compared with traditional thermoplastic elastomers, such as polyurethane elastomers (TPU) [8] and polyester elastomers (TPEE), [9] TPAEs exhibit excellent mechanical properties, low density, good elasticity and flexibility, and wider high and low temperature range of use, which makes it more and more popular in the fields of electronic, electrical, automotive, construction, household, and daily life.…”
