PLA2002D: pellets were purchased from NatureWorks LLC (Minnetonka, Minn. USA) and had a melt viscosity about 1500 Pa-s (190° C. and 100s−1), a melt point maximum endotherm at 150° C., and crystallinity generated with a second 10° C./minute heating of pellets previously heated to complete melting at 250° C. and cooled to 20° C. of about 0.5 J/g. PLA2002D is described by the supplier as having a major portion of L-lactide and about 4.3 to 5% “non L-lactide”. Behenamide: Crodamide° BR available from Croda Inc, Edison, N.J. EBAGMA: an autoclave-produced ethylene/n-butyl acrylate/glycidyl methacrylate terpolymer (monomer ratio 66.75 wt % ethylene, 28 wt % n-butyl acrylate, 5.25 wt % glycidyl methacrylate), melt index 12 g/10 minute, 190° C., 2.16 kg load as measured by ASTM method D1238, melting range 50° C. to 80° C. EBA: a tubular-reactor produced ethylene/n-butyl acrylate dipolymer (monomer ratio 73 wt % ethylene, 27 wt % n-butyl acrylate), melt index 4 g/10 minute, 190° C., 2.16 kg load as measured by ASTM method D1238; melting point 94° C.
