Effect Of Various Additives On The Properties Of Poly(L-Lactic Acid)/Poly(Butylene Succinate-Col- Lactate) Blend
Polymer blends of poly(L-lactic acid) (PLLA) and poly(butylene succinate-co-Llactate) (PBSL) at various blending ratios were prepared through melt mixing method. The blending of PLLA with PBSL resulted in an improvement in the toughness and thermal stability of the PLLA blend. However, flexural str...
