Epoxidized cardanol-based prepolymer as promising biobased compatibilizing agent for PLA/PBAT blends

Epoxidized cardanol-based prepolymer (ECP) generated from cashew nut shell liquid (CNSL) was successfully used as biobased compatibilizer/chain extender for poly (lactic acid) (PLA)/poly (butylene adipate-co-terephthalate) (PBAT) (80:20 wt%) blends. The reactive compatibilization effectiveness of di...
