実験手順

Polymerization of styrene with the system NaNH2 and triethylene glycol monobutyl ether. Polymerization is allowed to proceed from 8.32 g (8·10-22 mole) of styrene in in 30 cc THF in the presence of 0.98 g (25·10-3 mole) of sodium amide and 1.71 g (8.3·10-3 mole) of triethylene glycol monobutyl ether. The reaction mixture which is obtained prior to the addition of the monomer has a yellow color which is more pronounced than that obtained with diethylene glycol monoethyl ether, contrary to the results which have been obtained with glycol monomethyl ether. At the end of four hours, a polymer is obtained in 50% yield, with Mn=8500.
