Which describes a characteristic of branched polymers? a. they have only one start point and many end points. b. they have many start points as well as many end points. c. they have many start points and only one end point. the more detail the better you

B.They have many start points as well as many end points.

Explanation:

In a branched polymer side chains grow out of a main chain. The side chains are also made of same units as the main chain. These branches are a result of side reactions that occur during polymerisation.

The branches may serve as the starting or the end point of the chain. They may also be branched further. So the starting and the ending point of a branched polymer completely depends on the reference point. Branched polymers have reduced density because of lower packing efficiency.

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day

i think that you are smart and you should fit for it out
