In this work,by a combination of controlled ring-opening polymerization(CROP)and click reaction,we reported a facile and useful method to synthesize linear poly(ε-caprolactone)at attapulgite nanocomposites with well-defined structures.For this,first,the chlorine terminated attapulgite was prepared by the self-assembly of 3-chloropropyltrimethoxysilane from the surfaces of attapulgite.And then,the terminal chlorines of modified attapulgite were substituted with azido groups.As the second step,linear propargyl-terminated poly(ε-caprolactone)(PCLs)with different molecular weights were synthesized by the CROP of ε-CL monomer in toluene with Sn(Oct)2 as a catalyst and propargyl alcohol as an initiator.Finally,the azido-terminated attapulgites were reacted with propargyl-terminated PCLs via the click reactions.
