EFECTO DE LA ADICIÓN DE POLÍMEROS DE CADENA CORTA SOBRE LA ESTRUCTURA QUÍMICA, PROPIEDADES MECÁNICAS, TÉRMICAS Y BIOLÓGICAS DE POLIURETANOS SINTETIZADOS CON DIISOCIANATOS ALIFÁTICOS Y ACEITE DE HIGUERILLA

The objective of this research was to synthesize biocompatible polyurethanes, with suitable mechanical properties to be used as biomaterials. Polyurethanes were synthesized with polyols derived from castor oil and isophorone diisocyanate (IPDI), hexamethylene diisocyanate and 4,4’-methylenebis (cyclohexyl isocyanate), with the addition of polycaprolactone/chitosan (PCL/Ch). The materials were evaluated for their mechanical properties by determining the stress-strain curves, thermogravimetric analysis, differential scanning calorimetry analysis and contact angle. The biological response of th...
