Abstract: The purpose of this study was to investigate benzocyclobutene (BCB) derivatives as non-toxic curing agents to replace accelerated sulfur systems in certain synthetic biomedical materials. Prototype artificial spinal discs have been made and implanted in a few patients from a carbon black-filled copolymer of 1-hexene and 5-methyl-1,4-hexadiene (MHD), which is sulfur cured. The polymers investigated in this study were composed of 1-hexene, allyl-BCB, and MHD (or 7-methyl-1,6-octadiene, MOD). Curing was effected through reactions on BCB, forming carbon-carbon crosslinks. Preliminary cytotoxicity tests showed the material to be non-toxic, and the physical and mechanical properties of the BCB-cured materials were comparable with those of the sulfur-cured polymers.
