Summary: | Provided are a preparation method for a polyurethane optical resin and applications thereof. The preparation method for the polyurethane optical resin comprises: a raw material composition comprising isocyanate and a polythiol compound undergoes a polymerization to produce the polyurethane optical resin. The turbidity value of the isocyanate used in the raw material composition is controlled at ≤ 2 NTU. The polyurethane optical resin produced is applicable in manufacturing optical products. |
