Polyphosphazene
R
Calculate the following
a) Contour length
b) <R?>12 for a freely-jointed chain
c) <R?>12 for a free-rotation chain
d) <R?>12 for a restricted-rotation chain
Assume that the bond angle is the average of different bond angles (i.e., average over the P-N=P
and N=P-N bonds) in the polymer backbone, and <cosq> = 0.56.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1ccbd5b8-7004-4eac-8f28-afceab0bd4ca%2F4be562af-ed15-4549-ae66-c3474168d0c1%2Fw5mt4k_processed.png&w=3840&q=75)
