Notes:
Triethylene glycol dimethacrylate, TEGDM, was cured to various dose levels (0.15-2.0 Mrad) by γ-irradiation at 40°C and its dynamic mechanical properties were evaluated. The resultant products had up to four transition phenomena dependent upon dose. The highest temperature transition (IV) was due to the ultimate glass transition. Transition III (ca. 40°C) was due to additional reaction occuring just above the cure temperature. Transition 1 (ca. -60°C) occurred at low doses and was associated with residual monomer. Transition II (ca. -10°C) is due to association of —(CH2CH2O)— units in TEGDM monomer, and the associated regions persist in the crosslinked polymer.
