Abstract
The use of tin dibutyl dilaurate for the preparation of crosslinked polyether urethanes changes the rules of thermal decomposition (reduces the activation energy and pre-exponential factor, changes the order of the reaction) and weakens the dependence of activation parameters of the reaction on crosslinking density. The addition of low molecular weight diol to polyurethane compositions increases the activation energy and pre-exponential factor of thermal decomposition.
