Abstract

Vetri organici ad alto indice di rifrazione sono ottenuti per reticolazione di composizioni liquide contenenti una resina uretanica, rappresentata dalla formula di struttura (I), (FORMULA I) dove R, R1 , R2, R3, X ed n hanno il significato riportato nel testo; tale resina è diluita con uno o più composti reattivi di tipo acrilato e/o metacrilato e/o stirenico.I vetri organici ottenuti per reticolazione termica di tali composizioni sono caratterizzati dall'avere buona trasparenza, durezza e lavorabilità oltre ad un indice di rifrazione nd, misurato a 20°C, che è compreso tra 1,54 e 1,60.
