study on the effect of molecular structure on the photoinitiatedpolymerization of acrylates was undertaken. Initially, the research was focused on the effect of hydrogen bonding, and it was found that preorganization via hydrogen bonding enhances the maximumrate of polymerization (Rp). This hydrogen bonding facilitated preorganization also affected the tacticity of the resultant polymer. Next, the
对分子结构对丙烯酸酯光引发聚合反应的影响进行了系统的研究。最初,研究的重点是氢键的作用,发现通过氢键进行的预组织可提高最大聚合速率(R p)。这种氢键促进的预组织也影响了所得聚合物的立构规整度。接下来,研究了由给定单体的计算偶极矩(μcalc)表示的极性影响。观察到R p与计算的玻尔兹曼平均偶极矩(μcalc)之间存在直接的线性关系。的[R p -μ计算值相关性适用于纯单体,单体混合物,甚至单体与惰性溶剂的混合物。这种相关性使得能够合理设计具有所需反应性的单体。另外,这些研究表明,聚合的传播步骤受氢键的影响,而偶极矩则影响终止速率常数。可以将这两种机理解释视为影响丙烯酸酯聚合速度的互补因素。

日期:——
Products of the thermal and photosensitised autoxidation of N-alkyl- and NN-dialkyl-amides have been identified. N-n-Alkylamides yield principally N-acylamides, primary amides, and N-formylamides, as a result of initial abstraction of a hydrogen atom from the carbon adjacent to nitrogen. Formation of N-formylamides, and of N-acylamides from N-s-alkylamides, involves C(1)–C(2) bond scission in an N-alkyl
