    • To determine the precipitant for poly(NBocAAm, we conducted SEC analysis of poly(NBocAAm) prepared in acetone at 0°C The 0.1 g of the polymerization mixture after the removal of acetone was dissolved into 1 mL of THF, poured into diethyl ether containing 0, 25, and 50 of hexane (40 mL, The fractions of smaller molecular weights were not collected, when the polymerization mixture was poured into diethyl ether containing haxane less than 50 Thus, we determined hexane: diethyl ether (50:50 as the precipitant for poly(NBocAAm)s

Thus, we determined hexane: diethyl ether (50:50 vol:vol) as the precipitant for poly(NBocAAm)s.
