Compounded polymer materials usually contains many kinds of additives and is often used after forming intractable three-dimentional network structures. In this work, pulse-pyrolysis of sample materials followed by high-resolution gas chromatographic separation combined with mass spectrometric identification was successfully applied to elucidate the micro-structures of various intractable compounded polymer materials.1) The network structures of various styrene-divinylbenzene copolymers were systematically investigated.2) The curing processes of various epoxy resins were studied.3) The curing processes of various rubber materials were studied.4) Thermal degradation behabior of a series of polyesters was systematically studied.5) Thermal degradation mechanisms and compositional analysis of polyurethane binder polymers for magnetic tapes were studied.6) The molecular weight dependence of the short-chain branchings in low-density polyethylenes was systematically investigated.7) Thermal degradation mechanisms of thermally stable aromatic polyamides were studied.
