✦ Synopsis

The effect of radiation curing (5 kCi @'Co) on the aging behaviour of hydroxyl terminated polybutadiene-base propellant-binder system is studied. The elastomeric products were investigated for their mechanical properties, such as tensile strength, elongation, etc. After 2 years of aging the values of these properties did not alter significantly and remained better than for the aged samples which were cured thermally (65°C). Binders prepared using HTPB synthesized by different suppliers indicated distinct differences between them after aging.

## Abstract The ageing behaviour of trimethylolpropane trioleate was investigated at different temperatures in a modified rotary bomb test apparatus. Some physicochemical properties of ageing oil samples, such as acid value, kinematic viscosity, and iodine value, were measured. The oil samples were
