1 Approved Answer
A 5 0 g sample of poly ( amide 6 ) [ Nylon 6 ] produced by ideal step - growth polymerization of the monomer
A sample of polyamideNylon produced by "ideal" stepgrowth polymerization
of the monomer is found to contain mol of end groups by nuclear
magnetic resonance NMR
a Calculate the numberaverage molecular weight of this sample of Nylon
b Calculate the extent of reaction of the stepgrowth polymerization.
c Assuming "ideal" stepgrowth polymerization statistics, calculate the weight
average molecular weight.
d Estimate the weight fraction of chains in this sample that have a molecular weight
less than HINT: integration may be necessary Molar mass of P is gmol It is CHON
