Its structure should not be confused with polybutylene, a high molecular weight polymer with a different chain repeat unit.

This is incorrect, although I know what the author was trying to say. There is no difference between "polybutene" and "polybutylene". "Butylene" is simply an older from of the name "Butene".

The sentence should read "Its structure should not be confused with that of polyisobutylene, a polymer with a different chain repeat unit".

Polyisobutylene is a homopolymer of isobutylene only, whereas "polybutene" is a copolymer of n-butylene and isobutylene. Furthermore, polyisobutylene doesn't necessarily have to be high molecular weight, it exists in lower molecular weight/oligomeric forms as well.

Cat cracker[edit]

The phrase "cat cracker" should be studied. Not only must this be an epic "statistically improbable phrase," it came very close to being an assumed vandalized portion of the article. Perhaps the phrase could be better stated to be "reformed" by a "catalyst" or some alternative construct. I am just a bit nonplussed thinking about cat crackers. Here is the sentence I am referring to:

Polybutene is typically made from cat cracker mixed C4s (after the stream is Merox treated to remove sulfur and amines, and contain 1-butene, 2-butene, and isobutylene.

What an explosive, furry mouthful. I like to saw logs! (talk) 07:00, 19 August 2018 (UTC)[reply]
