摘要：
It is shown that cross-linking of the oligomer Al{[OSi(CH3)2]290OH}3 involves terminal hydroxyl groups and is accelerated by the introduction of metalloporphyrazines into the oligomer. The reaction is described by the first-order kinetic equation for irreversible reactions. The effective cross-linking rate constants at 180, 190, and 200°C and the activation energies of the reaction are calculated. A protective material with vulcanized coating based on oligoalumosiloxane has high fire resistance.
