Synthesis structure and properties of poly(ether

Polyurethanes are synthesized through the reaction of di- or poly-isocyanates high molecular weight polyols and low molecular weight chains extenders [1 2] but it is also possible to synthesis of PUs by non-isocyanate route [3 4] Currently polymers are prepared from components which are derived from petroleum [5 6] Renewable substances proposed for the synthesis of polymers are for

Polypropylene glycol or polypropylene oxide is the polymer of propylene glycol Chemically it is a polyether and more generally speaking it's a polyalkylene glycol (PAG) The term polypropylene glycol or PPG is reserved for low to medium range molar mass polymer when the nature of the end-group which is usually a hydroxyl group still matters The term oxide is used for high molar mass
