The active amine hydrogen equivalent weight of the ATBN was about 900 g/eq.
The raw materials were divided into two streams, the DGEBA + ATBN stream and the TETA stream, to prevent the reaction during the sample preparation step.
The morphology of the ATBN modified epoxy resin molded within the disc-type mold was investigated using scanning electron microscopy (SEM).
The cure kinetics of the ATBN modified epoxy resin during cure was investigated using a differential scanning calorimeter (DuPont 910 DSC and 990 thermal analyzer).
The viscosity rise of the ATBN modified epoxy system during cure was measured with an RMS (rheometric mechanical spectrometer) parallel plates geometry.
In this study, the ATBN modified epoxy system was investigated, and the balance equations for the RIM process were solved simultaneously by computer using the explicit FDM.
(7) compared the morphology and impact strength of the epoxy resin modified with two types of liquid rubbers, ATBN and CTBN.
In the previous paper (18), the curing and phase separation behavior of ATBN modified epoxy resin was investigated.
The liquid rubber employed was amine terminated butadiene acrylonitrile random copolymer (ATBN: Hy-car 1300X16 from BF Goodrich) which contained 16 wt% acrylonitrile.
and 90 [degrees] C and with varying ATBN contents of 5, 10, 15, 20, and 30 wt%.
The compatibility between DGEBA and ATBN system was already reported in the previous study (18) through cloud point measurements.
