Polymer Edge
Are the edges of any polymer(star with a simple one like poly-ethene) is attached with each another? or do they have other thing attached with it? Like, (-CH2-CH2-CH2-CH2-)n we have more -CH2- beside each edge on that structure; but what is the structure of the last portion of it? for example in fullerin we have 60 carbon atoms joined like a sphered shaped ball and we can visually see that there's no other compound than C and H.
