Cross‐linking of amidated polybutadiene with resole. II.

摘要

AbstractTo prove the main cross‐linking reaction between amidated polybutadiene and resole, cross‐condensation reactions involving simple amide compounds and resole were examined. Amide compounds having both an amide group and a carboxylic acid group inhibited the self‐condensation of resole itself. The cross‐condensation products obtained from succinamic acid and 2‐methylolphenol were separated using a preparative chromatography method to identify the cross‐condensed products in which the main products were cross‐condensed oligomers having an imide linkage. A cross‐condensation scheme was proposed, and it was concluded that the main cross‐linking reaction between amidated polybutadiene and resole also followe
