Abstract
The catalytic effect of Fe(AA)3 on polymerization of HTPB-IPDI system was investigated. It was found that the reaction of HTPB-IPDI system obeys the pseudo-second order reaction law and the dependence of the rate constant on Fe(AA)3 concentration is parabolic while the addition of small amounts of acetylacetone (HAA) to the Fe(AA)3 catalyzed reaction causes a hyperbolic response. The experimental results obtained are as follows: (1) In both cases of low molecular weight alcohol-isocyanate system and high molecular alcohol-isocyanate system, the reaction obeys the Bruenner''s mechanism. (2) Activation energies of HTPB-IPDI system are 13.63 kcal/mole for uncatalyzed reaction and 12.57 kcal/mole for Fe(AA)3 catalyzed reaction.
