| Abstract: | A series of transparent casting polyurethane resin (TCPU) were synthesized from cycloaliphatic diisocyanate (H 12 MDI), polyol, chain extender, crosslinking agent, catalyst and special aids (T). They were characterized by FTIR. The thermal stabilities of the obtained TCPU were examined by DSC and TGA. The morphologies fractured surfaces of TCPU were revealed by SEM. The crystalline amorphous characters of TCPU were studied by WAXD. The optical properties of TCPU were studied by a visible light absorbance measurement. The mechanical properties of TCPU were measured. The results showed that it had excellent mechanical properties. |
