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.
