Resumen
The production of polymers is strongly linked to the use of petroleum as the main raw material. Cross¬linked polymeric materials, such as polyurethane, have great applications in various industrial sectors, but the high degradation time of this polymer due to the raw material used represents a serious environmental problem. Added to this, the oils from chicken slaughtering, mainly from offal and hides, have also been causing environmental impacts due to their incorrect disposal. Thus, this work presents an innovative synthesis of biodegradable polyurethanes from residual chicken oil. The obtaining of the polyurethane resin was identified from the analysis of infrared spectroscopy, thermogravimetry and differential scanning calorimetry, in which it was possible to observe functional groups characteristic of this type of polymer, besides waterproofing properties. In view of this, tests were conducted on the applicability of the synthesized resin for coating and protecting wood, such as accelerated aging and contact angle analysis, showing a greater efficiency when compared to a commercial beeswax.
