WebAn example of a backbiting reaction that creates the short chain branches is shown in Fig. 18.5. In this example the growing end of a polyethylene chain turns back on itself and abstracts a hydrogen atom from the carbon atom located four bonds away from the chain end, as shown in Fig. 18.5 a). Chain growth proceeds from the newly formed unpaired … Webthe propyl branch. The presence of butyl branches in the ethylene/1-hexene copolymers was estimated from the intensities of the signals at, 1. 14.2 ppm due to the methyl carbon (C1) of the butyl branch, and 2. 23.34 ppm due to the C2 methylene carbon of the branch. Other resonances due to the methine carbon (Br) at ~38 ppm and the C4 methylene
