The grafting of isoprene onto poly(propylene oxide)


  • Presented at the Third Northeast Regional Meeting of the American Chemical Society, Buffalo, N. Y., October 11, 1971.


The grafting of isoprene as well as a comonomer mixture of isoprene and acrylonitrile onto a backbone of high molecular weight poly(propylene oxide) with tertiary-butyl peroctoate gave a gumstock which is sulfur curable to a product having interesting elastomeric properties.
