Structure-property insights of semi-aromatic polyamides based on renewable furanic monomer and aliphatic diamines

Process Cascade for the Production of Green Polymers from CO2 and Electric Energy

“…1), making it unfeasible to use a SSP for increasing the molecular weight into regions necessary for a subsequent processing of the polymer. Though the lack of crystallinity seemed surprising at the first view, the amorphous character of polyamides from FDCA is also described for other diamine units in the polyamide chain [66]. In order to still achieve the target of synthesizing high molecular weight polyamides 5F, a classical polycondensation of a 5F salt would be a possibility.…”

Controllable Synthesis of Furan-Based Poly(ester amide)s and Its Study on Adhesive and Aggregation-Induced Emission Properties

“…To counter mass transfer limitations, laboratory-scale thin film reactors were employed effectively to facilitate the diffusion and removal of volatiles. Compared with the traditional reaction in a bottom flask, the M n of the polymer increased by 55%. , Besides, solution polycondensation was an appealing alternative approach to suppress side reactions at high temperatures above 200 °C. ,, The solution polycondensation had access to operate under less severe reaction conditions with a much lower temperature and standard atmospheric pressure. The polar aprotic solvents like N , N -dimethylformamide (DMF), N -methyl pyrrolidone (NMP), and N , N -dimethylacetamide (DMAc) were extensively reported due to their good solubility for polymers.…”

Preparation of chemically recyclable bio-based semi-aromatic polyamides using continuous flow technology under mild conditions

“…Compared with traditional reaction in flask, the M n of the polymer increases by 55%. 10,11 Moreover, Kanan et al synthesized furan-based poly(5-aminomethyl-2-furoic acid) using direct solid-state polymerization (SSP). The resulting polymer had greater molecular weight and dispersity (M n = 30.6 kDa and Đ = 1.76).…”
