Application of products of reaction between melamine and glycidol as substrates for oligoetherols and polyurethane foams containing 1,3,5-triazine rings

摘要

Hydroxyalkyl derivatives of melamine were obtained by addition of melamine to glycidol. These derivatives were then used to obtain multifunctional oligoetherols by reaction with oxiranes and alkylene carbonates. The structure and properties of the oligoetherols were studied in detail. The oligoetherols were then used to obtain polyurethane foams of enhanced thermal stability. The foams showed marked thermal resistance at 200 °C. The beneficial feature of the obtained foams was their increased compression strength after thermal exposure.
