30. n, for the poly(olefin) derivatives were determined by end group analysis, which is accurate to ca. 30 000 amu. All poly(olefins) used in this study were within this range.
31. n = 1.65.
32. Theoretical molecular weights are calculated by assuming that one alkoxyamine initiating group leads to a single polymer chain, the degree of polymerization of which is governed by the ratio of styrene to initiator. The polymerizations are run to 90% conversion.
