摘要：

Effects of carboxyl-terminated butadiene acrylonitrile rubber (CTBN) on the cure characteristics of diglycidyl ether of bisphenol A (DGEBA)/4,4'-methylene dianiline (MDA)/phenyl glycidyl ether (PGE)-acetanide (AcAm) system were studied by autocatalytic cure rate expression. Cure rate at initial stage increased with the increment of the CTBN content, however, at some high stage cure rate was inverted due to the diffusion control of formed CTBN domain. The total conversion was also decreased with the increase of the CTBN content. (C) 1998 Elsevier Science S.A.
