Abstract
Poly(methyl methacrylate) (PMMA), poly(diallyl phthalate) (PDAP) and nine poly(MMA-DAP) standard samples whose compositions were known were investigated by means of pyrolysis capillary gas chromatography(Py-CGC) and their pyrolysis products were identified by pyrolysis capillary gas chromatography-mass spectrometry(Py-CGC/MS). The relationship between monomer feed ratio in copolymer and quantity of pyrolysates was drawn in a standard working curve. On these bases, the structure and composition of 14 cutting plates of a poly(MMA-DAP) GRIN material polymerized by a vapor transfer diffusion technique were analyzed by Py-CGC.
