Question #50273

Answer 1

Photo initiated free radical polymerization to form a methyl branched polyether.

Explanation:

`n CH(CH_3) = CH(CH_3)` + `gamma` => `I-CH(CH_3)C*H(CH_3)`

`I-CH(CH_3)C*H(CH_3)` + `O = C(CH_3)_2`
=> `I-CH(CH_3)CH(CH_3) - O - C*(CH_3)_2`

=> `I-CH(CH_3)CH(CH_3) - O - C(CH_3)_2 - [- CH(CH_3)CH(CH_3) - O - C*(CH_3)_2 ]_n ... -> ("terminated")`

This, of course, assumes perfect alkene to ketone sequencing without mixture segments of the butene interfering.
