萘与硫在较低温度下交联聚合 ,制得了可溶性好、残炭值高、软化点较低、流动性良好的交联萘沥青。结构分析发现 ,此沥青分子量分布较窄 ,主要由三到四个萘分子交联而成。推测其反应机理 ,估计聚合物经萘环侧位交联成环而形成长链状硫杂环类结构。 Naphthalene and sulfur were cross-linked and polymerized at lower temperature to prepare cross-linked naphthalene pitch with good solubility, high carbon residue, low softening point and good fluidity. Structural analysis shows that the asphalt has a narrow molecular weight distribution and is mainly composed of three to four naphthalene molecules crosslinked. Presumably the reaction mechanism, it is estimated that the polymer is cross-linked by the naphthalene ring to form a long-chain thioheterocyclic structure.
