Biodegradation of 2-HEMA-g-Na-PCMS a polymeric matrix synthesized from natural modified carbohydrates

摘要

2-Hydroxyethyl methacrylate (2-HEMA) was graft copolymerized with sodium salt of partially carboxymethylated starth (Na-PCMS). Thus, prepared graft copolymer (2-HEMA-g-Na-PCMS) and pure Na-PCMS were evaluated for their biodegradable character. The Lycopodia fungi were utilized as microorganism and sucrose solution as the growth medium. Biodegradation medium was prepared from fungus Lycopodia sucrose solution. Percent weight loss and SEM photographs showed biodegradation in this graft copolymers and Na-PCMS in order of 32% and 80% respectively. Results are compared with the biodegradation data obtained with previously biodegraded samples. Results are discussed with illustrations.
