Abstract:

Based on the nature of the anionic-to-Ziegler Natta transformation reaction employed, the subsequent fractionation and the characterization of the product, and particularly the transmission electron microscopy of the morphology of the polymer produced, it is concluded that a 1,4 polybutadieneisotactic polypropylene diblock copolymer has been produced. Certain properties and potential uses of this copolymer are discussed in this preliminary report. Author
