Abstract

SE DESCRIBE UN PLASTICO FOTOCROMICO OPTICAMENTE TRANSPARENTE REALIZADO A PARTIR DE MATERIALES QUE CONTIENEN AZUFRE Y CONTENIENDO COMPUESTOS ORGANICOS FOTOCROMICOS PRODUCIDOS MEDIANTE PROCESO DE POLIMERIZACION COMO COMPONENTES SOLIDOS. LOS COMPUESTOS ORGANICOS TIENEN AL MENOS DOS SISTEMAS ANULARES ENLAZADOS MEDIANTE UN ESPIROATOMO DE CARBONO. SU ACCION DE TINTADO FOTOCROMICO ES DEBIDO A LA RUPTURA REVERSIBLE DEL ENLACE AL ESPIROATOMO DE CARBONO.
