Abstract

Quantitative solid-state13C-NMR was used to investigate the chemical reactions in blends of poly(4-vinyl phenol) (PVPh) with diglycidylether of bisphenol-A (DGEBA) at high temperatures. The PVPh/DGEBA blends (in absence of cure agents or catalysts) upon heating developed a cross-linked structure. However, the reacted product was hardened/cross-linked and not amenable to solution-NMR characterization. In order to gain more insight into the mechanisms proving the chemical reactions between the epoxide of DGEBA and phenol of PVPh, studies were performed using compounds containing an epoxide group to model the DGEBA monomer and compounds containing an phenol group to model the actual PVPh polymer. The1H- and13C-solution-NMR spectroscopy characterizations demonstrated that chemical reactions between the model compounds. The results showed that the opening of the epoxy ring occurred, transforming the original epoxide ring to a phenyl-ether carbon linkage. The use of the model compounds clearly revealed a mechanism where the phenol group of PVPh reacted with the epoxide of DGEBA leading to a gelled/cross-linked structure.
