Naming Polymer Structures: A Quick Guide

Click For Summary

Discussion Overview

The discussion revolves around the naming of a specific polymer structure, with a focus on substituted polyenes and copolymers. Participants explore the implications of substitution on the polymer's nomenclature and synthesis.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests the polymer is a substituted polyene, noting that hydrogen atoms are replaced with other groups, but expresses uncertainty about its existence.
  • Another participant questions the feasibility of the polymer's existence and discusses potential structures, indicating that if it is a copolymer, it would resemble the attached image.
  • There is a suggestion that the polymer could be synthesized similarly to Kevlar, although one participant expresses skepticism about the synthesis process.
  • One participant proposes a specific name for the polymer, poly[(1E,3E)-3,4-diamino-1,3-butadiene-1,2-diol], while questioning the complexity of substituted polyenes.
  • A later reply raises the issue of whether substitution occurring after the formation of the polyene could lead to nomenclatural challenges.

Areas of Agreement / Disagreement

Participants express differing views on the complexity and feasibility of the polymer structure, with no clear consensus on its existence or the implications of substitution on its naming.

Contextual Notes

Participants do not fully resolve the assumptions regarding the synthesis of the polymer or the specific conditions under which substitution occurs.

How would I name the polymer in the attached image?

that is some kind of substituted polyene :-) hydrogen atoms are substituted with other groups, but I'm not sure that this exists
 
Why wouldn't it exist?

if it will be copolymer, it will look like attached image, or if it is substituted polyene, it will something more complicated. Also looks like you want to make something like Kevlar but I cann't imagine how are you going to synthesize this polymer.

No, it's the latter; just a simple substituted polyene :smile:

Also, why would a substituted polyene be more complicated?
It's just (–C(NH2)=C(NH2)-C(OH)=C(OH)–)n (a conjugated polyene)

Ahh...that might be a good question for another thread...

But as far as this thread is concerned, would its name be something like poly[(1E,3E)-3,4-diamino-1,3-butadiene-1,2-diol]?

ok, what about this kind of structure (if substitution occures after forming polyene).

What about it? Would opportunities for substitution pose nomenclatural problems?
