Like Phenol (C 6 H 5 OH) and Urea {(NH 2 ) 2 C=O)}, Furfuryl alcohol (C 4 H 3 OCH 2 OH), a product of agricultural origin is capable of polymerization with Formaldehyde (H 2 C = 0) under suitable PH conditions. However, usable polymers, at least as no bake for Foundry applications are obtained only when the condensations are carried out in association with Urea, Phenol or both. The series of re...

There is a growing interest in the development polymers based on renewable resources1-2. Polyurethanes constitute a kind of materials that can vary from rubbery to glassy thermoplastics from linear polymers to thermoset. This versatility can be further controlled in terms of processing and composition to fulfil a great versatility that permit the manufacturing of products ranging from expanded ...
