1.0 INTRODUCTION 1.1 Research Background Polyurethane was first produced and investigated by Prof. Dr Otto Bayer (1902-1982). He is also recognized as the “father” of the polyurethanes industry for his invention of the basic diisocyanate polyaddition process. The versatility of this new organic polymer and its ability to substitute for scarce materials make it suitable for many applications. There are various types of polyurethanes, which might look and feel very different from each other. They have been used in a diversity of products, from coatings and adhesives to shoe soles, mattresses and foam insulation. However, the basic chemistry of each type of polyurethanes is essentially the same. Polyurethane is one of the versatile polymers mainly…show more content…
As the petroleum prices are gradually increases from time to time, the alternatives to find the substitute for it becoming interest and hence can conserve this non renewable resource from scarcity. The concern to substitute this raw material in making polyurethanes is not only due to petroleum prices gradually increase, but also in concern of our environment due to the polyurethanes might be toxic if it is improper mixing with other chemicals. The unreacted chemicals might be release in the environment and make their way into waterways and hence pollute the open surface water like river. The aquatic organisms inhabit this river will eventually die due to suffocating. By substituting polyester to polyether, it can give the potential for the polyurethanes produced degrade easily due to ester functional group present in the structure. This ester functional group can provide the potential for fungus or bacteria to decompose the polyurethane. Polyester polyols can be obtained from natural products such as palm kernel oil, soybean oil and cooking oil. From the previous studies done, the polyurethanes made from polyester polyols are as comparable as polyurethanes made from polyether polyols. In addition, in regards of our concern on the high production of waste cooking oil that being dump illegally in the river and landfills worldwide, the study made to reuse the waste…show more content…
In addition, it will also provide awareness in people especially manufacturers on preserving our environment by using renewable resources which will reduce the production cost and have the potential to degrade easily. It is believed that the productions of polyurethanes from agricultural products would cost manufacturer much cheaper compared to petroleum products. 1.4 Objectives of the
