Three types of petroleum-based tricycloalkyl-containing methacrylate polymers derived from adamantane and DCPD were synthesized and characterized, poly(1-adamantyl methacrylate) (PADMA), poly(tricyclodecyl methacrylate) (PTCDMA) and poly(1-adamantyl methacrylate-co-tricyclodecyl methacrylate) (P(ADMA-co-TCDMA)). As expected, the incorporation of a tricycloalkyl substituent as a pendant group on the methacrylate polymer contributed to enhancement of thermal stability in combination with high transparency in the UV–vis region and long-term thermal resistance, in addition to improved mechanical properties, a lower CTE, decreased water absorption and a lower dielectric constant. These merits make tricycloalkyl-containing methacrylate polymers promising candidates for use as high value-added optical plastics in the microelectronics and optoelectronics applications.
