Bisphenol-A polycarbonate (BAPC) dendritic crystals were formed through the melt crystallization induced by dioctyl phthalate (DOP) at high pressure. The cultured dendrites belong to a three-dimensional structure with different characteristics. The dendritic growth was found to be accelerated with the increase of the applied temperature, pressure, crystallization time and DOP concentration. This finally resulted in the formation of the structures of the spatial cellular dendrites in the investigated BAPC/DOP system.
