Transparent polyamide (TPA) is a type of optically transparent material with high performance, and poly(decamethylene terephthalamide) (PA10T) is an emerging bio‐based opaque polyamide. With the purpose of preparing bio‐based and low‐cost TPA based on PA10T, we chose dodecanedioic acid and isophthalic acid as comonomers, and successfully obtained a series of transparent PA10T/10I/1012. The basic properties of these copolyamides were characterized by intrinsic viscosity measurement, Fourier transform infrared spectrometer, proton nuclear magnetic resonance, X‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis, dynamic mechanical analysis, ultraviolet–visible spectrophotometer, solvent resistance test, water absorption measurement, and tensile measurement. Results show that PA10T/10I/1012 copolymers are amorphous and have high optical transparency. Moreover, these copolymers exhibit high thermal stability, low water absorption, and good solvent resistance, and they also show better mechanical properties compared to some commercial TPAs. © 2018 Wiley Periodicals, Inc.
