Polystyrene is a synthetic polymer with the structure - (CH2- CH (C6Hs)), A batch of polydisperse polystyrene was prepared by initiating the polymerization with t-butyl radicals. As a result, the t-butyl group is expected to be covalently attached to the end of the final products. A sample from this batch was embedded in an organic matrix containing silver trifluoroacetate and the resulting MALD1- TOF spectrum consisted of a large number of peaks separated by 104 g mol-1, with the most intense peak at 25578 g mol-1. Comment on the purity of this sample and determine the number of (CH2-CH (C6Hs)) units in the species that gives rise to the most intense peak in the spectrum.
