Biodegradable poly(ester amide)s (PEAs) were synthesized from lactic acid and 11-aminoundecanoic acid via melt polycondensation. Molecular weights. chemical structures and thermal properties of the poly(ester amide)s were characterized in terms of gel permeation chromatography (GPC). Fourier transform infrared spectroscopy (FTIR). https://safeersappliancers.shop/product-category/samsung-rr39m7340b1-eu-tall-fridge-black/
