DMA plots of storage modulus versus temperature for (a) samples irradiated at 100 kGy containing varying BQ composition and 20% PETA, (b) samples irradiated at varying doses containing 10,000 ppm BQ and 20% PETA, and (c) samples irradiated at 100 kGy containing varying % PETA and 10,000 ppm BQ. Rubbery modulus increased most significantly with increasing PETA. Rubbery modulus also increased with increasing dose, and decreased slightly with increasing BQ composition.
