  • Sulfur modified polyvinyl acetate (PVAc)
    Patent number: 9243167
    Abstract: Provided are a sulfur modified polymer composition, free from asphalt, bitumen or like compounds, and method of making same. The inclusion of 50% by weight sulfur, or greater, into the polymer composition results in a composition that is softer and having an increased melting point, relative to the unmodified polymer composition.
    Type: Grant
    Filed: February 7, 2013
    Date of Patent: January 26, 2016
    Assignee: Saudi Arabian Oil Company
    Inventors: Ibnelwaleed A Hussein, Mohammed H Al-Mehthel, Hamad I. Al-Abdul Wahhab, Saleh H. Al-Idi, Mohammed A. Suleiman
