Versuchsvorschrift

To a 1-liter, one-neck flask were added naphthalene (45 grams) and lithium shot (5.1 grams) in mineral oil. The flask was equipped with a magnetic stir bar, and was then capped with a rubber septum. After an argon purge, freshly distilled tetrahydrofuran (300 milliliters) was then added by cannula under argon and the mixture was stirred for 16 hours. The molarity of this initiator solution was 2.38 molar as determined by an average of the GPC molecular weight results from six polymerization reactions.
