Abstract

The present work is concerned with the preparation of polyurethane elastomers. Polyurethane elastomer was prepared by the bulk polymerization via one 4,4'diphenyl methane polypropylene glycol using stannous octeate as a catalyst. The operating conditions of the polymerization were studied and their affects on the mechanical properties of the prepared elastomer. with 4,4'diphenyl methane diisocyanate to equivalent of polypropylene glycol (NCO/OH)

(1.5- 3), and curing temperature of about mechanical properties of polyuretha elastomers were: Kinetic of the reaction also was studied using adiabatic temperature rise method. The overall order of reaction was of the reaction was frequency coefficient of reaction ( (mole/g mixture)
