Editing Polymer (section)

== Etymology ==
The term "polymer" derives {{ety|el|''πολύς'' (polus)|many, much||''μέρος'' (meros)|part}}. The term was coined in 1833 by [[Jöns Jacob Berzelius]], though [[Jöns Jacob Berzelius#New chemical terms|with a definition]] distinct from the modern [[IUPAC]] definition.<ref>If two substances had molecular formulae such that one was an integer multiple of the other – e.g., acetylene ({{chem2|C2H2}}) and benzene ({{chem2|C6H6}}) – Berzelius called the multiple formula "polymeric". See: Jöns Jakob Berzelius (1833) "''Isomerie'', Unterscheidung von damit analogen Verhältnissen" (''Isomeric'', distinction from relations analogous to it), ''Jahres-Bericht über die Fortschitte der physischen Wissenschaften …'', '''12''': 63–67. [https://books.google.com/books?id=1vs4AAAAMAAJ&pg=RA1-PA64 From page 64]: "Um diese Art von Gleichheit in der Zusammensetzung, bei Ungleichheit in den Eigenschaften, bezeichnen zu können, möchte ich für diese Körper die Benennung ''polymerische'' (von ''πολυς'' mehrere) vorschlagen." (In order to be able to denote this type of similarity in composition [which is accompanied] by differences in properties, I would like to propose the designation "polymeric" (from ''πολυς'', several) for these substances.)<br />Originally published in 1832 in Swedish as: Jöns Jacob Berzelius (1832) "Isomeri, dess distinktion från dermed analoga förhållanden," ''Årsberättelse om Framstegen i Fysik och Kemi'', pages 65–70; the word "polymeriska" appears on [https://books.google.com/books?id=PZUHAAAAcAAJ&pg=PA66 page 66].</ref><ref>{{cite journal |author=Jensen, William B. |author1-link=William B.
