聚苯硫醚又称聚苯撑硫、聚次苯基硫醚,英文缩写PPS,其外观为白色或微黄色粉末,熔点280~290℃,平均分子量为1万~5万,交联后呈热固性,其结构为苯环和硫的重复相连,结构式(C6H4S)n。由于苯环结构的刚性和耐热性以及苯环与硫之间化学键的稳定性,赋予其许多优异的性能,是一种新型工 Polyphenylene sulfide, also known as polyphenylene sulfide, polyphenylene sulfide, the English abbreviation PPS, the appearance of white or yellowish powder, the melting point of 280 ~ 290 ℃, the average molecular weight of 10,000 to 50,000, was Thermosetting, the structure of the benzene ring and sulfur repeatedly connected, structural formula (C6H4S) n. Due to the rigidity and heat resistance of the benzene ring structure and the chemical bond stability between the benzene ring and the sulfur, many excellent properties are given to it, which is a new type of work
