Low molar mass cyclic poly(l-lactide)s: separate transesterification reactions of cycles and linear chains in the solid state

Abstract

L-Lactide (LA) was polymerized with neat tin(II) 2-ethylhexanoate (SnOct2) in toluene at 115 °C at low concentration with variation of the LA/Cat ratio. Cyclic polylactides (cPLAs) with number average molecular...
