A fully nature-originated poly(carboxy decanediamine) (PUA10) was synthesized from pressurized carbon dioxide and 1,10-decanediamine, which acted as the monomers. Hot isostatic press (HIP)-molding was attempted using powdered PUA10 sample, and the crystal structure as well as physical properties of the molded specimens were investigated. The crystal structure of PUA10 was found to be more perfect after HIP-molding, which is most likely related to the crystallization that occurs under the pressurized conditions. PUA10 crystals generated at atmospheric pressure showed a Brill transition-like crystal phase transition at 145 °C and had a melting temperature of 225 °C. To the contrary, PUA10 crystals generated via the HIP-molding melted at 250 °C. The HIP-molded PUA10 specimen had a compressive yield stress greater than 110 MPa, which is greater than those of various polyamide (PA) polymers. However, the coefficient of thermal expansion (CTE) of HIP-molded PUA10 at around 100 °C was about 30.3 × 10⁻⁵ K⁻¹, which is much larger than the CTEs of PA6 and PA66 (10–14 × 10⁻⁵ K⁻¹) in the same temperature range.

由加压的二氧化碳和作为单体的1,10-癸二胺合成了完全源自自然的聚（羧基癸二胺）（PUA10）。尝试使用粉末状PUA10样品进行热等静压（HIP）成型，并研究成型样品的晶体结构和物理性能。在HIP成型后，发现PUA10的晶体结构更加完美，这很可能与在加压条件下发生的结晶有关。在大气压下生成的PUA10晶体在145°C时显示出类似于Brill转变的晶体相变，熔融温度为225°C。相反，通过HIP成型生成的PUA10晶体在250°C时熔化。经HIP成型的PUA10样品的压缩屈服应力大于110 MPa，大于各种聚酰胺（PA）聚合物。但是，HIP模制的PUA10在约100°C时的热膨胀系数（CTE）约为30.3×10^-5 K ^-1，比相同温度范围内PA6和PA66的CTE大（10-14×10 ^-5 K ^-1）。
