Magnetism and Electro-Magnetism,distribution . at temperatures below -65°C. The coupling reaction between iodine-terminated living polypropylene and monofunctional living polystyrene anion was examined at 50°C and shown to result in the quantitative formation of monodisperse AB block copolymer of propylene and styrene. In addition

Expansion, Gas Laws and Kinetic Theory,Although highly active polymerization catalysts prepared from TiCl. supported on MgCl. and aluminum alkyls have been used for the stereospecific polymerization of propylene since the early seventies, . no report has appeared up to now concerning the polymerization of racemic α-olefins with this type of catalytic system.

Selectivity in Addition Polymerization,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.

,Some Aspects of Coordination Homo- and Copolymerization of High α-Olefins, Cyclic and Allene Hydrocaused a revolution in macromolecular chemistry which has meant that many of the established notions have had to be reconsidered and has given rise to new works and ideas in the polymerization of the carbochain and hetero-atomic monomers.

,‘Colours and Cries, Buff and Blue’,on of isotactic enchainments of the monomeric units is brought about. Owing to “the third generation catalyst”, polypropylene industries are achieving dramatic innovation in terms of productivity and of energy conservation. Mechanistic elucidation of the role of the catalyst components, such as MgCl
