Flexible PLA Copolymers with Low Melt Flow Index for Blown Film Applications
A series of strategies are investigated, which allow internally plasticized polylactide (PLA)‐polyether block copolymers to be effectively melt‐processed through blown film extrusion in the semi‐technical scale. Among the strategies presented are the use of tris(nonylphenyl) phosphite (TNPP) as a chain extender during the ring opening polymerization (ROP) of lactide and the application of ε‐caprolactone (CL) as a plasticizing comonomer. The produced films have a significantly higher flexibility than pure PLA films and are in a comparable range to the flexibility of fossil‐based, film‐grade low‐density polyethylene (LDPE) films.
