As the elemental analysis does not show the presence of oxygen atom, it can be concluded that the final AFAAC does not contain oxygen but if in Step 3 (Scheme 3) formaldehyde reacts with product (b) then the final product should contain -OH group at either of the ends.
The viscosity results of AFAAC are summarized in Table 2.
Modification of mechanical properties like impact, adhesive, tensile, and flexural occurred by incorporation of AFAAC into epoxy resin.
This was because in two-step process, the reaction between AFAAC and epoxy was maximum, i.
To correlate the molecular and morphological parameters with the fracture properties of the toughened networks, the microstructure of the fracture surfaces for AFAAC modified networks were analyzed by SEM.
Thermo-Mechanical Analysis of AFAAC Modified Epoxy Networks
The unmodified epoxy and AFAAC modified epoxy networks in the two-step process were subjected to DMA analysis.
The thermogravimetric (TG), differential thermogravimetric (DTG), and differential thermal analysis (DTA) diagram of AFAAC modified (12.
