| Summary: | Studies on the polymerization of acetaldehyde by the catalyst of aluminumtriethyl are reported. It was found that there were several remarkable differences between the polymerizations when catalyst was added at room temperature and at low temperature. In this polymerization system, the conversion reached a limited value in relatively short time. There was a maximum of conversion at 2%(wt) of catalyst to monomer. The lower polymerization temperature, the greater polymerization rate and the larger fraction of crystalline polymer became. An apparent activation energy of over all polymerization in this system was calculated to be-8.5 kcal/mol. |
