Abstract:
A carbon-containing modified polystyrene type resin particle of the present invention includes: a carbon-containing polypropylene type resin, and a polystyrene type resin in an amount of not less than 100 parts by weight but less than 400 parts by weight per 100 parts by weight of the carbon-containing polypropylene type resin, wherein the polystyrene type resin ratio at the central part of the particle is at least 1.2 times the polystyrene type resin ratio of the overall particle, the polystyrene type resin ratio being calculated by using the ratio (D698/D1376) of absorbances at 698 cm−1 and 1376 cm−1 which are obtained by infrared absorption spectra measured by ATR infrared spectroscopic analysis.
Abstract(Chinese):

本发明的含碳改性聚苯乙烯类树脂颗粒包括：含碳聚丙烯类树脂和聚苯乙烯类树脂，其量不小于100重量份但小于400重量份，相对于每100份 含碳聚丙烯类树脂的重量，其中颗粒中心部分的聚苯乙烯类树脂比例为总颗粒的聚苯乙烯类树脂比的至少1.2倍，聚苯乙烯类树脂比通过使用比例（ D698 / D1376），其通过通过ATR红外光谱分析测量的红外吸收光谱获得的698cm -1和1376cm -1处的吸光度。
