PBS is partially crosslinked by using DCP as an initiator. A low gel fraction (<30 wt%) and low crosslink density of the partially crosslinked PBS are obtained at a DCP content of <0.5 wt%. Consequently, the partially crosslinked PBS retains both its processability and its crystallinity. The overall crystallization rate of the PBS is enhanced by partial crosslinking as evidenced by a considerable increase in crystallization temperature (T c ). Meanwhile, the mechanical properties of PBS are significantly improved by the partial crosslinking. The structure/property relationships of the partially crosslinked PBS are explored.
