Mechanical and Thermomechanical Properties of Nylon6T/66/PPS Blends

Abstract

Polymer blending is a very important and widely used method for the modification of polymer materials. However, little attention has been paid to the Semi-aromatic Polyamides with PPS blends. In this article, we investigate the properties of Poly (phenylene sulfide) (PPS) blends with Poly (hexamethylene terephthalamide/hexamethylene hexanediamide) (nylon 6T/66). The structure, mechanical properties of nylon 6T/66 and (PPS) blends were studied by scanning electron microscopy (SEM), Differential scanning calorimetry (DSC) and Thermogravimetric analysis (TG). The results indicate that the blends have good thermal stability and the tensile strength, flexural strength and flexural modulus of the blends are better than the PA6T/66 but worse than that of the PPS.

Polymers without Petrochemicals: Sustainable Routes to Conventional Monomers

“…Semiaromatic polyamides such as PA6T and PA6I, derived from 1,6-HDA with terephthalic or isophthalic acid, respectively, are heat resistant polymers with high melting and glass-transition temperatures, high rigidity, and low water absorption. 1350 Recent work by Shen et al synthesized PA5F and PA10F, novel semi-aromatic polyamides of 2,5-FDCA with 1,5-PeDA and 1,10-decanediamine, respectively. 1351 Both polyamides showed high thermal stability (i.e., up to 380 °C), with PA5F showing a relatively high T g of 86 °C and PA10F exhibiting a lower T g of 35 °C, and were identified by the authors as potentially useful materials for bio-based 3D-printing applications.…”

“…Partially or fully aromatic polyamides, termed aramids if >85% of the amide linkages are between two aromatic rings, are very high-performance polyamides, with aerospace and military applications such as Kevlar for bulletproof vests. Semi-aromatic polyamides such as PA6T and PA6I, derived from 1,6-HDA with terephthalic or isophthalic acid, respectively, are heat resistant polymers with high melting and glass-transition temperatures, high rigidity, and low water absorption .

High heat resistance and good melt spinnability of a polyamide 66 containing benzene structure

“…21 For combining the properties of various polymers, copolymerization or blending method is generally used. [22][23][24] For example, Wang et al synthesized PA6T/6 (50:50) copolymers with high content of the rigid aromatic units, which shows improved thermal stability and mechanical properties. 25 Qu et al obtained PA6T/2T copolymer and found the melting temperature decreased from 368 o C for PA6T to 347 o C for PA6T/2T copolymer.…”
