Abstract:
1. A method of preparing a polymer having a lone electron pair-containing moiety thereon, comprising: reacting a polymer of formula (I) wherein R R L LG is a leaving group selected from the group consisting of  wherein R mesylate; brosylate; tresylate, and nosylate; and n is 0 or positive integer, with a compound of Formula (III) in an aqueous base at a temperature of from about 45 to about 50° C. and for a reaction time of less than about 18 hours, wherein the compound of Formula (III) is wherein Z is NR X is O, S or NR m is a positive integer; R R provided that R the aqueous base is selected from the group consisting of NaOH, KOH, LiOH, Mg(OH) wherein 10 molar equivalent of compound of Formula (III) is employed for each equivalent of LG; and the purity of the polymer having the lone electron pair-containing moiety thereon formed by said method is greater than 95%.
