Research Abstract |
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.
