In the three systems, system realizes the crosslinking of PVC bases on the peroxide crosslinking mechanism, the tensile strength of crosslinked PVC has been improved somewhat, the IR spectrum of gel demonstrates that there are characteristic absorption peaks of n-alcohol that belongs to ethanol amine and benzenoid group. From the analysis of gel structure , deduces that the mechanism of crosslinking reaction: under the initiations of peroxide and high temperature, PVC yields macromolecules free radicals, at the same time , styrene"s polymerization and grafting onto PVC takes place, at last the system forms crosslinking structure through coupling between radicals; confirms that triethanol amine can absorb HC1 produced by degradation of PVC, so improves the crosslinking efficiency of peroxide, decreases the HCl"s promotion for PVC"s degradation; deduces that triethanol amine can activate the PVC macromolecules and prolong the free radicals" life-time of PVC macromolecules; the effect to the PVC macromolecule makes styrenes graft reaction easy, and thus improves the crosslinking efficiency.

三种体系中三乙醇胺/过氧化二异丙苯/苯乙烯体系基于过氧化物交联机理实现了聚氯乙烯的交联，聚氯乙烯交联后拉伸强度有一定提高，凝胶红外光谱分析证实了凝胶结构中含有乙醇胺的伯醇基团特征吸收和苯环的特征吸收，由凝胶结构分析，推断出交联反应的机理：聚氯乙烯在过氧化物和热作用下产生大分子自由基，苯乙烯在过氧化物和大分子自由基的作用下发生聚合和接枝反应，最终通过自由基之间的偶合产生交联；证实三乙醇胺可以吸收聚氯乙烯分解产生的HCl，提高了过氧化物的交联效率，消弱了HCl对聚氯乙烯降解的促进作用；推断三乙醇胺可以活化聚氯乙烯大分子并有可能使聚氯乙烯大分子自由基存在的时间得以延长，对聚氯乙烯大分子的作用使苯乙烯的接枝反应易于发生，从而提高了交联效率。

The spectrum peaks nearby 530nm and 480 nm are corresponding with BTSD and BMD respectively. It is found from measurement that the luminescence peak from BMD is bluely shifted. The atoms of BTSD nearby dislocation core are affected by tensile stress along the Burger's vector direction leading to its band gap narrowed. In addition, there is the effect of part quantity of edge dislocation in BMD existed. Part of atoms in BMD are strained by compressive stress leading to its band gap narrowed, in other words, the wavelength from BMD is shorter than that from BTSD.

从测试结果中还发现BMD 的发光位较BTSD有所蓝移，分析认为BTSD位错芯附近原子沿伯格斯矢量方向只受到拉应力，致使禁带宽度变窄，BMD由于除了具有螺型位错的分量外还具有部分刃型位错的分量，而刃型位错中有部分原子受到压应力的作用，导致禁带宽度增宽，从而使得BMD的发光波长比BTSD短
