ABSTRACT

The synthesis of polyetherols based on (hydroxypropyl)cellulose, functionalized with glycidol, and ethylene carbonate was elaborated. All conversions were performed in glycols. The products were characterized by IR, 1H NMR, and MALDI ToF spectroscopy. The polyetherols were then used to obtain rigid polyurethane foams. These foams have apparent density, water uptake, and polymerization shrinkage similar to classic rigid polyurethane foams. The foams showed advantageous thermal resistance in comparison with classic ones. After thermal exposure their compressive strength was improved.

带有纤维素亚基的聚醚醇和聚氨酯泡沫

摘要

阐述了基于缩水甘油和碳酸亚乙酯官能化的基于（羟丙基）纤维素的聚醚醇的合成。所有转化均在乙二醇中进行。通过IR，1 H NMR和MALDI ToF光谱对产物进行表征。然后将聚醚醇用于获得硬质聚氨酯泡沫。这些泡沫具有与经典的硬质聚氨酯泡沫相似的表观密度，吸水率和聚合收缩率。与传统泡沫相比，该泡沫显示出有利的耐热性。热暴露后，它们的抗压强度得到改善。
