Modification of Low Refractive Index Polycarbonate for High Refractive Index Applications

<table>Polymerization of the composition consisting of (i) Polythiol (PSH), (ii) Toluene diisocyanate (TDI),  and (iii) Diethylene glycol di(allyl carbonate) (DEGDAC). The reaction between PSH and TDI, in the presence of DBTDL results in the formation of a polythiourethane.</table>
