AI Technical Summary
Existing polyurethane technologies face challenges in producing high-performance materials from renewable resources due to difficulties in maintaining softness over time, environmental issues with plasticizers, and the need for economically viable production times, while also achieving mechanical properties comparable to petroleum-based products.
The use of a copolymer of poly(farnesene) diol and a cyclic lactone or ether as the polyol component in polyurethane formulations, which allows for the incorporation of renewable materials and maintains hardness over time, with industrially feasible production cycles.
This approach enables the production of polyurethanes with mechanical properties comparable to commercially available elastomeric materials, while retaining hardness and achieving Shore A hardness of 75 or less, with improved processing times and reduced environmental impact.
