Synthesis and characterization of tricyclodecyl-containing methacrylate polymer for optoelectronics applications

Abstract Tricyclodecyl-containing methacrylate polymers based on tricyclodecyl methacrylate (TCDMA), namely poly (tricyclodecyl methacrylate) [P (TCDMA)] and poly (tricyclodecyl methacrylate- co -methyl methacrylate) [P (TCDMA- co -MMA)], were synthesized by free radical polymerization. Homo- and copolymer were characterized by Fourier transform infrared (FTIR) and 13 C NMR spectroscopy. The effects of structural design on the thermal, mechanical, dielectric and optical properties of synthetic polymers were studied. Compared to polymethyl methacrylate (PMMA), the incorporation of a tricycloalkyl substituent as a side group on a methacrylate polymer helps to improve thermal stability, while providing high transparency and long-term heat resistance in the UV–visible region. In addition to improving mechanical properties, the coefficient of thermal expansion (CTE), water absorption and dielectric constant are reduced. These advantages make tricycloalkyl-containing methacrylate polymers promising candidates for use as high value-added optical plastics in optoelectronic applications.
