本文深入研究了苯乙烯高聚物的光物理行为,进一步证明了在苯乙烯/二乙烯苯交联凝胶中形成的苯基多环聚集体不仅存在于激发态也存在于基态,不仅可在苯乙烯/二乙烯苯交联凝胶中形成,也可在非均匀结构线型高聚物中形成。这种苯基多环聚集体的形成可归因于高分子链的化学交联和物理交联等产生的“超浓结构”,反映了苯乙烯高聚物结构的非均匀性。
In this paper, the photophysical behavior of styrenic polymers has been studied in depth. It is further demonstrated that the phenyl polycyclic aggregates formed in the styrene / divinylbenzene crosslinked gels exist not only in the excited state but also in the ground state, Styrene / divinylbenzene cross-linked gel formed, but also in non-uniform linear polymer structure formed. The formation of this phenyl polycyclic aggregate can be attributed to the “super-dense structure” produced by the chemical and physical crosslinking of the polymer chains, which reflects the heterogeneity of the structure of the styrene polymer.
