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

Explanation:

n CH(CH_3) = CH(CH_3)nCH(CH3)=CH(CH3) + gammaγ => I-CH(CH_3)C*H(CH_3)I−CH(CH3)C⋅H(CH3)

I-CH(CH_3)C*H(CH_3)I−CH(CH3)C⋅H(CH3) + O = C(CH_3)_2O=C(CH3)2
=> I-CH(CH_3)CH(CH_3) - O - C*(CH_3)_2 I−CH(CH3)CH(CH3)−O−C⋅(CH3)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.
