Abstract: The present invention provides a soot-suppression flame-separation combustion device for combustion calorimetry and in-situ free radicals monitoring. The combustion device is mainly composed of a premixed combustion gas guide tube, an inner flame generating seat, an oxidation flame separation guide, and a sample combustion chamber; the inner flame generating seat is arranged in the premixed combustion gas guide tube, the oxidation flame separation guide is arranged on the premixed combustion gas guide outlet end of the premixed combustion gas guide tube, the sample combustion chamber is a cavity arranged inside the oxidation flame separation guide, and the oxidation flame separation guide is evenly arranged with at least 4 oxidation flame separation guide paths in a manner of surrounding the sample combustion chamber. The combustion device utilizes the special structure of the oxidation flame separation guide to suppress the generation of smoke and limit the smoke particles to a specific combustion area, thereby reducing the interference of sample combustion smoke on the spectral diagnosis method and improving the applicability of spectral diagnosis in sample combustion monitoring.

Abstract: A copolyester, comprising structural units represented by [I], [11], [111] and [IV]. The number of structural units represented by [III] is 1-99% of the number of structural units represented by [I], and the number of structural units represented by [IV] is 0-99% of the number of structural units represented by [I]. Also provided are a preparation method therefor and an application thereof. Because an introduced high-temperature self-crosslinking group and an ion group can improve the melt viscosity and the melt intensity during burning of a copolyester, and effectively enhance the char-forming capability of the copolyester, the copolyester exhibits excellent flame retardance and anti-dripping performance. The preparation process for the copolyester is mature, convenient to operate, and easy to control and apply to industrial production.
