Thermal polymerisation of liquid allene affords two dimers, 1,2-dimethylenecyclobutane and 1,3-dimethylene-cyclobutane, as well as three trimers, 1,5(and/or 1,6)-dimethylenespiro[3,3]heptane, 1,2,4-trimethylenecyclohexane and 3-methylenebicyclo[4,2,0]octa-1(6)-ene. A radical mechanism is proposed.
液态丙二烯的热聚合可提供两个二聚物,1,2-二亚甲基环丁烷和1,3-二甲基-环丁烷,以及三个三聚物,1,5(和/或1,6)-二亚甲基螺[3,3]庚烷,1 ,2,4-三亚甲基环己烷和3-亚甲基双环[4,2,0]八-1(6)-烯。提出了一种激进的机制。
