刚才少了一个 at the second phase

As shown in Table 2, the content of phosphorus and nitrogen in epoxy resin increased gradually with the increase of hexaaminophenoxy content. Though the initial decomposition temperature and initial rapid decomposition temperature exhibited a slight decrease, the thermostability at the second phase and carbon residue at high temperature showed an obvious increase. This plays important role in moderating the rapid combustion of epoxy resin at high temperature and increasing the self extinguishing character of the resin. It is also the key factor for using phosphorous element especially phosphorus nitrile as intumenscent flame-retardant agent.
