Fully Chemical Recyclable Poly(y-butyrolactone)-based Copolymers with Tunable Structures and Properties
文献摘要：
The emerging chemical recyclable polymers,such as poly(y-butyrolactone)(PGBL)and poly((R)-3,4-trans six-membered ring-fused GBL)(P((R)-M)),provide a good solution to the plastic pollution.However,these homopolymers suffer from limited structures and properties.Herein,we reported a fully chemical recyclable copolymer P(GBL-co-((R)-M))through ring-opening copolymerization(ROCOP)of GBL and(R)-M.By employing organomagnesium as the catalyst and regulating the reaction conditions,the chemical structures of copolymers were well-controlled(GBL content=13％-78％,Mn=6560-15600 g/mol,DM=1.08-1.59).The resultant P(GBL-co-((R)-M))exhibited fully chemical recycl-ability,which rapidly and quantitatively depolymerized into initial GBL and(R)-M monomer through chemolysis.By varying GBL content,tun-able thermal properties were achieved for P(GBL-co-((R)-M)).The onset decomposition temperatures of copolymers varied from 193℃to 234℃.A linear evolution of glass transition temperature(Tg)of P(GBL-co-((R)-M))versus GBL content was obtained as following equation of Tg=-1.06 x GBL mol％x 100+39.6.We hope that the reported fully chemical recyclable copolymers with tunable structures and properties would serve as the candidate material for sustainable applications.
