Question:

The vulcanization of polyisoprene is accomplished with sulfur atoms according to Equation 15.4. If 45.3 wt% sulfur is combined with polyisoprene, how many cross-links will be associated with each isoprene repeat unit if it is assumed that, on the average, five sulfur atoms participate in each crosslink?
