Polymers Derived from a Poly ether, 2,4-Toluene Diisocyanate, and Octamethylcyclotetrasiloxane

摘要

Polymers prepared from a polyether, 2,4-toluene diisocyanate, and octamethylcyclotetrasiloxane were studied using thermomechanical analysis, mechanical tests, and water vapor adsorption. The adsorption of nitrogen vapor was studied at 77 K, and that of water vapor, at 293 K.
