โœฆ Synopsis

The methodological problem of correct eathuttion of invariant Arrhenius parameters d and &

from nonisothermal experiments has been analyzed for thermal decompoaition of commercial butyl rubber in inert atmosphere. It is Shown that res<nctionpf the kinetic analysis by varying n in the function / ( a ) = (1a)" may yield incorrect A and E. It is necesary to ap@y the set of f ( a ) known in the formal topochemical reactions kinetics for correct estimation of A and 8.

Analyzing the transformation-degree dependence of the effective activation energy, we have studied the thermolysis gross kinetics of polypropylene ( PP ) -based fire-resisting composition and a synergetic mixture of fire-retardant additives: antimony oxide and hexabrominecyclododecane (HBCD). The ad
