Abstract
There is now provided a sealant and elastomer made with a polyol having an unsaturation level of 0.04 to 0.07, manufactured with a basic salt of an alkaline earth metal or a basic salt of cesium, such as cesium hydroxide. The elastomers and sealants made therefrom exhibit an increasing modulus of elasticity when strained from 100 percent elongation to 300 percent elongation. The reduced unsaturation polyols are simple and inexpensive to make while imparting good physical properties to the sealants and elastomers.
