Blends of poly(L-lactic acid) (PLLA) and poly (butylene terephthalate-co-adipate) (PBTA) were prepared at ratios of 50 : 50; 60; 40; and 80 : 20 by melt blending in a Laboplastomill. Improved mechanical properties were observed in PLLA when it was blended with PBTA; a biodegradable flexible polymer; Irradiation of these blends with an electron beam (EB) in the presence of triallyl isocyanurate (TAIC); a polyfunctional monomer; did not cause any significant improvement in the mechanical properties; although the gel fraction increased with the TAIC level and dose level. Irradiation of the blends without TAIC led to a reduction in the elongation at break (Eb) but did not show a significant effect on the tensile strength. Eb of PBTA was unaffected by EB radiation in the absence of TAIC. © 2008 Wiley Periodicals; Inc;
