Polyoxymethylene/thermoplastic polyamide elastomer blends: Morphology, crystallization, mechanical, and antistatic properties

Abstract

Polyoxymethylene/thermoplastic polyamide elastomer (POM/TPAE) blends were prepared through melt extrusion in an attempt to improve the toughness and electrical properties of POM. The TPAE used in the study had the permanent antistatic effect, and its brand was MV2080. Acrylonitrile-butadiene-styrene copolymer grafted maleic anhydride (ABS-g-MAH) was added while preparing the POM/TPAE blends to improve the compatibility between TPAE and POM. The effects of TPAE and ABS-g-MAH on the morphologies, melting crystallization, dynamic mechanical analysis, surface resistivity and mechanical properties were examined in detail with various techniques. It was found that after adding 15 phr MV2080 as the modifier, the distribution of MV2080 in the blends was presented as many continuous long strips, which can be called “antistatic networks.” When using ABS-g-MAH as a compatibilizer, the surface resistivity of the samples 5#, 6#, and 7# which all containing 15 phr MV2080 with the best antistatic properties reached 107 Ω, and the impact strength of the above samples was all increased by more than 66%.

Research progress of antistatic‐reinforced polymer materials: A review

“…Therefore, how to balance the mechanical properties and antistatic properties of the material would be the focus of future research. Fang et al 63 developed an antistatic thermoplastic polyamide elastomer (TPAE)/POM composite and researched the effect of acrylonitrile‐butadiene‐styrene copolymer grafted maleic anhydride (ABS‐MAH) as a compatibilizer on the antistatic properties of TPAE/POM. This result indicated that the conductive network formed by TPAE in the composites was more uniformly distributed after the addition of the ABS‐MAH, thus reducing the surface resistivity of the composites.…”

Synergetic impacts of two rigid nano‐scale inclusions on the mechanical and thermal performance of POM/carbon black/CaCO3 ternary nanocomposite systems

“…However, poor impact strength, high UV sensitivity, and low thermal resistances may restrict its further application. [1][2][3][4] To tailor the functionality of POM and extend its applications, several studies were conducted to achieve a higher toughness for POM composites reinforced by elastomers [5,6] and mineral fillers. [7,8] The toughening of POM by incorporating elastomers was reported in many studies.…”

Structure–property relationships and constitutive viscoelastic behaviors of polyether‐block‐amide elastomers in melt and solid states

“…PAEs have been used in thermoplastic blends as toughening agent or impact modifiers because they possess high impact resistance even at low temperatures 18–20 . Another important application of PAEs is as non‐migratory internal antistatic agent for many polymers such as polyethylene, polystyrene, polyoxymethylene 20,21 …”

Evaluation of viscoelastic properties of copolymers in solid and melt states is essential for understanding their processing operations and long-term physical properties for industrial applications.…”
