A Non-isocyanate Route to Poly(ester urethane) with High Molecular Weight: Synthesis and Effect of Chemical Structures of Polyester-diol

Zi-Yun Shen et al.

Summary: A series of non-isocyanate linear high molecular weight poly(ester urethane)s (PETUs) were prepared through an environmentally-friendly route, and their properties were characterized. The results showed that PETUs have high molecular weights and tensile strength, with the degree of phase separation being affected by crystallization and hydrogen bonding interaction.

Synthesis and characterization of the non-isocyanate poly (carbonate-urethane)s obtained via polycondensation route

Dominik Wolosz et al.

Summary: This paper presents a non-isocyanate synthetic route towards linear aliphatic and aliphatic-aromatic poly(carbonate-urethane)s, utilizing urethane diols as hard segment precursors and oligo(hexamethylene-co-pentamethylene carbonate) diol as soft segment precursor. The impact of polyurethane structure on mechanical and thermal properties was studied, revealing that the presence of pentamethylene carbonate units can improve reaction efficiency. Characterization of the poly(carbonate-urethane)s included spectroscopic analysis, spectrometry, thermal analysis, and mechanical testing, showing promising tensile strengths for both types of polymers.

Comparison of flexible polyurethane foams properties from different polymer polyether polyols

Irene Izarra et al.

Summary: The synthesized FPUs showed better hardness and density properties but worse mechanical properties compared to commercial products; FPUs containing PS as filler exhibited higher thermal stability and mechanical resistance than those with SAN filler; density and hardness are affected by filler type and content, with closed cell foams produced at filler contents exceeding 15%.

Trends in non-isocyanate polyurethane (NIPU) development

Alvaro Gomez-Lopez et al.

Summary: The transition towards safer and more sustainable production of polymers has led to a growing interest in non-isocyanate polyurethanes (NIPUs) as potential replacements for conventional materials. However, the challenges in directly replacing conventional polyurethanes (PUs) with NIPUs have been more difficult than initially anticipated. Despite significant academic research, the market size of NIPUs remains small, indicating a need for continued efforts to overcome limitations and promote industrial adoption.
