Conference Paper Description

Dispersion polymerization of L-lactide was proceeded in various ionic liquids. Ionic liquids as 1-Hexyl-3-methylimidazolium bis (trifluormethylsulfonyl) imide, [HMIM] [TFSI], 1-Butyl-3-methylimidazolium bis (trifluoromethylsulfonyl) imide, [BMP] [TFSI], and N,N,N-Trimethyl-N-Propylammonium Bis (trifloromethanesulfonyl) imide, [TMPA] [TFSI], were employed as reaction medium that dissolved both of lactide and stabilizer (polyvinylprrolidone). Sn-supported on bentonite was used as a ring opening catalyst of L-lactide. Gel Permeation Chromatography result showed that poly-(L-lactic acid) were formed in ionic liquids [HMIM] [TFSI] and [BMP] [TFSI] with molecular weight as 19390 and 20844, respectively.
