Síntesis y caracterización de poliuretanos usando como poliol aceite de ricino, glicerol y poliglicerol

En el presente trabajo se propone la síntesis de poliuretano empleando poliglicerol y aceite de ricino para aumenta la cantidad de hidroxilos del poliol y así modificar las propiedades morfológicas, fisicoquímicas, térmicas y mecánicas del material, con el objetivo de encontrar un material con un ba...

In the current paper
we proposed the synthesis of polyurethane using polyglycerol and castor oil
to increase the quantity of hydroxyls into the polyol and that way modify the morphological
physiochemical
thermal and mechanical properties of the material. With the objective of find a material with a low environmental impact
capable of compete with the offered from the petrochemical industry. Using self-condensation we produced two types of polyglycerols with different molecular weight and hydroxyl number. We made six reactions to produce polyurethanes at different polyol composition
changing the relations between castor oil
glycerol and polyglycerol. In the polyurethanes obtained
we evaluated properties using a Fourier Transform Infrared Spectroscopy (FTIR)
resistance to chemical reagents
water absorption
Thermogravimetric Analysis (TGA)
Differential Scanning Calorimetry (DSC)
hardness
impact resistance and a Dynamic Mechanical Analysis (DMA) static and dynamic. Changing the composition of polyglycerol inside of polyol
we obtained
different degrees of crosslink sites
generating materials with better tensil strength and elongation percent
which is related to the increase in the functionality of the hydroxyls. On the other hand it is denoted an increase in the material™s plasticity
due to the increase of the polyglycerol™s hyperbranched carbon chains. Finally the polymer's structure decrease the material's thermal stability.
