Experimental Study on Effects of Mechanical Properties of Lytag Concrete

Abstract:

Pyrolysis behavior of a new kind of polybenzoxazine with aldehyde groups was investigated by pyrolysis gas chromatography-mass spectroscopy (PyGC-MS) at the temperatures ranging from 450°C to 750°C. It was found from the pyrolysis chromatograms that the type and amount of its pyrolysates obviously change with pyrolysis temperature due to various pyrolysis behaviors at different temperatures. From the structures and relative contents of the pyrolysates, the pyrolysis mechanism of the polybenzoxazine was described as follows: the initial degradation reactions occurred mainly at the C_methylene-N bond, followed by the C_phenyl-C _methylene bonds.
