Abstract: Disclosed is a furan diacid-based polyamide resin, which is derived from the following repeating units: (A) 2,5-furandicarboxylic acid, (B) 1,4-cyclohexanedicarboxylic acid, and (C) 1,10-decanediamine, where based on the total molar percentage of the diacid units, (A) accounts for 5-45 mol% of the diacid units. On one hand, by selecting the bio-based 2,5-furandicarboxylic acid, the resin is more environmentally friendly, and has the advantages of a melting point of 290-336°C , low water absorption rate, and good size stability (a water absorption rate lower than that of a polyamide with the same amido bond density); on the other hand, the rigidity of cyclohexane is higher than that of an aromatic ring, such that more hard carbon layers can be formed during combustion. In addition, the furan diacid-based polyamide has a relatively high amido bond density, and can generate a relatively excellent synergistic effect with a flame retardant, such that the flame retardant effect is excellent under the synergistic effect of the two.

Abstract: A composition includes a thermoplastic resin including: a polypropylene polymer; and from about 0.15 wt% to about 4.75 wt% of a filler comprising carbon nanotubes. The carbon nanotubes have an average diameter of about 5-15 nanometers (nm), a surface area of at least about 100 square meters per gram (m2/gr), and a volume resistivity of 10-3 Ohm.centimeters (Ohm.cm) or lower. The composition exhibits a volume electrical resistivity between 2.0E+14 Ohm.cm and 1.0E+03 Ohm.cm, and a molded sample of the composition exhibits a percent Absorbed Power measured in Transmission mode of at least 65% at frequencies of from about 75 GHz to about 110 GHz. Molded articles including micron-sized features that provide the article with high absorption and low reflection properties are also described.
