The biodegradable cellulose-derived polyol and polyurethane foam
Polymer Testing, 2021 The method of polyol synthesis from cellulose, glycidol, and ethylene carbonate in water was elaborated. The obtained polyol was characterized by IR, 1H NMR and MALDI ToF spectroscopy. The polyol was then used to obtain rigid polyurethane foam. That foam

Rational Design of a Polyurethane Foam
Polymers, 2022 Polyurethane (PU) foams are exceptionally versatile due to the nature of PU bond formation and the large variety of polymeric backbones and formulation components such as catalysts and surfactants. This versatility introduces a challenge, namely a near unlimited number of variables for formulating foams.
