Supported Catalysts for Polypropylene: Aluminum Alkyl-Ester Chemistry,activity and stereospecificity. NMR investigations show that AlEt. alkylates ethyl benzoate by the following reaction: PhCO.Et + 3 AlEt. → 1/2 (Et.AlOEt). + Et.Al·Et.AlOCEt.Ph. The rate of ethyl benzoate consumption decreases with lower Al/PhCO.Et ratios. Atmospheric pressure polymerization studies

Japanese Companies Come to Britain,ter of a century. Despite the immense amount of industrial and academic effort expended, and despite much broad understanding of the factors involved, a full understanding of much of the detail of many aspects of selectivity in polymerization remains as a challenge to chemists.
