概要	Glycerol polyglycidyl ether (GPE) and polyglycerol polyglycidyl ether (PGPE) were cured with poly(L-lysine) (PL). When PGPE was used and the epoxy/amine ratio was 1/1, the cured neat resin showed the highest Tg. Next, the mixture of PGPE, PL and montomorillonite (MMT) at an epoxy/amine ratio of 1/1 in water was dried and cured finally at 110 degree C to create PGPE-PL/MMT composites. The XRDand TEM measurements revealed that the composites with MMT content 7-15 wt % were exfoliated nanocomposites. The Tg and storage modulus at 50-100 degree C for the PGPE-PL/MMT composites measured by DMA increased with increasing MMT content until 15 wt % and decreased at 20 wt %. The tensile strength and modulus of the PGPE-PL/MMT composites were much greater than those of the cured PGPE-PL resin. Aerobic biodegradability of the PGPE-PL in an aqueous medium was 4% after 90 d, and the PGPE-PL/MMT nanocomposites with MMT content 7-15 wt % showed lower biodegradability.
