Abstract
Flexible polyurethane nanocomposites (PUNCs) containing recycled polyether polyols received from chemical recycling of original corresponding foams were synthesized by the incorporation of organically functionalized Cloisite 30B montmorillonite (MMT). Different amounts of MMT (1-3%w) were added to the polyol mixture prior to introducing the isocyanate portion. Recycled polyol was ranged between 10 to 30% of total polyol and MMT was maximum 3%. Thermal, morphological and mechanical properties of prepared PUNCs were studied and the results demonstrated the improvement of properties.
