Abstract
La utilización
química y energética de los materiales obtenidos a partir de materias primas de
origen natural y renovable es actualmente una prioridad y se busca derivar
materiales que puedan sustituir parcial o totalmente los obtenidos del
petróleo, así como aportar nuevas propiedades.
En este
trabajo se presenta la síntesis y caracterización de materiales poliméricos con
propiedades funcionales y/o estructurales a partir de recursos naturales
renovables. Para ello se partió de un aceite de tung no modificado capaz de
entrecruzar con diferentes comonómeros insaturados por medio de polimerización catiónica.
Se sintetizó un conomómero a partir de modificación química del mismo aceite de
tung (transesterificación). Los materiales obtenidos usando estireno y el metil
ester de aceite de tung como comonómeros permitieron alcanzar un alto contenido
de componentes bio-derivados y mostraron capacidad de amortiguación mecánica y
propiedades dinámico-mecánicas comparables.
