Polyvinyl chloride
I've changed back your two edits to Polyvinyl chloride:
 * You removed "Technology" from the title of the book, but here I see that it is in the title
 * There is no need for "PVC" in section title "Discovery" in article on PVC, it's obvious enough (see Manual of Style) – attomir (talk &#124; contribs) 11:35, 16 June 2020 (UTC)
