A self-polymerizable liquid octatetrayne, 1,8-dibutyl-1,3,5,7-octatetrayne, was heated to 80 °C and
produced cross-linked poly(1,8-dibutyl-1,3,5,7-octatetrayne) microbeads via suspension polymerization
with diameters adjustable from hundreds of micrometers to a few micrometers. Carbon microbeads that
may be useful for catalyst supports or in high-performance carbon materials were obtained by the pyrolysis
of poly(1,8-dibutyl- 1,3,5,7-octatetrayne) microbeads at 800 °C under an inert atmosphere.
