Abstract

Un vetro organico con resistenza all'urto migliorata e con indice di rifrazione pari o simile a quello del vetro minerale (vetro crown), è costituito dal prodotto della polimerizzazione radicalica della composizione liquida polimerizzabile ottenuta per transesterificazione di:(A) diallil carbonato con una miscela dei polioli:(B) bis (2-idrossietiletere) del bisfenolo-A,(C) glicole dietilenico, e (D) tris (idrossietil) isocianurato,dove per ogni 100 parti in peso della somma dei polioli (B), (C) e (D), il poliolo (B) è presente in quantità da 20 a 60% in peso, il poliolo (C) è presente in quantità da 20 a 60% in peso ed il poliolo (D) è presente in quantità da 10 a 40% in peso; e dove il rapporto molare tra il diallil carbonato e la somma dei polioli (A) / (B) + (C) + (D) è pari o superiore a 3/1.
