In case of GR composites, GR layers are well exfoliated through ENR matrix and the particle size is smaller compared to GT filled composites, It is because of the good compatibility between oxygen functionalities on the surface of GR and epoxy groups
of isoprene units owing to the formation of hydrogen bonds, the exfoliated GR layers were indicated through arrow marks in TEM micrographs.
1]H NMR, it was determined that 97% of the epoxy groups
were consumed by reaction with acrylic acid.
An increase in the amount of mPEG in the resins decreased the reactive epoxy group
content in the coatings and decreased the crosslink density.
Taking into account that the conversion of epoxy groups
was not quantitative, f values were relative low with values ranging from 7 to 13 for the CE_Tx series.
78) Decker and co-workers studied the cationic photocrosslinking of diglycidylether of bisphenol A (DGEBA), bis-cycloaliphatic diepoxide (BCDE) and their mixtures with epoxidized soybean oil (ESO) containing three epoxy groups
in the molecule (ESO-3).
The aminated lignin, an aromatic amine hardener with a three-dimensional structure, needs elevated temperature to react with epoxy group
The absorption peaks of epoxy group
and free isocyanate group at 917 and 2277 [cm.
The intrinsic absoiption for the epoxy group
was observed at 914 [cm.
Identification of non-heme diiron proteins that catalyze triple bond and epoxy group
Thus, these results indicate that the glycidyl carbamate epoxy group
is more reactive than glycidyl ether epoxy groups
1] was chosen as an internal standard for the quantitative analysis , The quantitative calculation of epoxy group
content was used the ratio of peak area in 1250  and 1382 [cm.
Therefore, compared to EPPO that possessed only one epoxy group
on its end, PPOE could better improve the miscibility of blend owing to its greater reactivity and function of compatibilizer.
