Abstract

DTA and DSC data revealed that the use of heteropoly compound additives allows an increase in the temperature of polybismaleimide radical polymerization by 20–60 deg in comparison with the value for the initial olygomer. TG data showed that in the presence of certain amounts of the inhibitor the polymer thermoresistance does not decrease. The range of effective concentration of the inhibitor is 1–5 wt.%.

Zusammenfassung

Nach DTA und DSC-Befunden kann die Anwendung von Zusätzen von Heteropolyverbindungen die Polymerisationstemperatur um 20–60° erhöhen. Nach TG-Ergebnissen nimmt die Wärmebeständigkeit des Polymers in Gegenwart kleiner Inhibitormengen nicht ab. Der Inhibitor wirkt in einer Konzentration von 1–5 Gew.%.

Резюме

Согласно данным ДТА и ДСК, использование в качестве добавок гет ерополисоединений приводит к повышению температуры радикал ьной полимеризация полиб исмалеинимида на 20–60° по сравнению с и сходным олигомером. С огласно же данным ТГ, наличие н ебольших количеств ингибитор а не вызывает уменьше ния термоустойчивости п олимера. Концентраци я ингибитора в 1–5 весовы х продента является н аиболее эффективной.
