Microstructural analysis of poly(vinylidene fluoride) using benzene derivative pyrolysis products

► Key pyrolysis products of PVDF to determine the microstructures were benzene derivatives. ► 1,3,5-Trifluorobenzene was generated from the head-to-tail sequence. ► 1,4-difluorobenzene was formed from the tail-to-tail one. ► 1,2,4-Trifluorobenzene was formed from the head-to-head and tail-to-tail serial sequence.
