A series of styreneated polyols have been prepared from unsaturated glycol glycoside and argemone oil. Upto 50% by weight. styrene was loaded by generating free radical onto hydroxyl functionalised polyester, using. AIBN as initiator. The extent of unsaturation in styrenated polyols was determined by its Iodine Value. its molecular weight was determined by Gel Permeation Chromatogram (GPC) and functional group by Infrared Spectroscopy. A series of such prepared styrenated polyols was mixed with an aromatic adduct based on toluene di isocyanates (TDI) in different ratios of their equivalents (OH: NCO) to form Two Pack Polyurethane. Polyurethane resin thus prepared was coated on test panel and were compared with a set of unstyreneated polyols and isocyanate adduct admixtures for Flexibility. Scratch hardness. Impact resistance, % Adhesion and Chemical resistance. Structure of the polyurethane was confirmed by FTIR. Thermal stability of styreneated polyurethane was determined and compared with unstyreneated polyurethane by TGA. |
