本文研究了在烷基苯磺酸作用下,环化橡胶类感光性高分子光交联产物降解反应的动力学行为。测定了在链长不一的烷基苯磺酸作用下,降解反应的级数和降解反应的活化能,讨论了烷基的链长以及烷基链长不一的苯磺酸浓度对降解反应速率的影响,提出了降解反应的增溶机理,证实了十二烷基苯磺酸对环化橡胶类感光性高分子光交联产物的降解反应有较大的促进作用。
In this paper, the kinetic behavior of photodegradation reaction of photo-crosslinkable products of cyclopropene-based photosensitive polymers under the action of alkyl benzene sulfonic acid was studied. The series of degradation reaction and the activation energy of degradation reaction were determined under the action of alkylbenzene sulfonic acid with different chain lengths. The effects of alkyl chain length and benzene sulfonic acid concentration on the degradation reaction The mechanism of solubilization of degradation reaction was proposed. It was confirmed that dodecylbenzenesulfonic acid could greatly promote the degradation of the photo-crosslinked photopolymer of cyclized rubber.
