Microstructure of diene polymers

Early work on the microstructurc of the diene polymers has been reviewed.1 While polymerizations of a large number of 2-substituted and 2,3-disubstituted dienes have been reported,88 little is known about the microstructure of diene polymers other than PB,89 polyisoprene,90 and polychloroprene.91... 

Our experimental data enable us to state that the microstructure of diene polymers obtained with 7r-allylic systems depends on the character of metal-carbon bonds between the transition metal and the growing chain end.
