Synthesis and characterization of functionalized modified PVC-chitosan as antimicrobial polymeric biomaterial
Autor: Samira T. Rabie, Reham A. Abdel-Monem, Osama M. Darwesh, Samir T. Gaballah
Publikováno v: Polymer Bulletin.
Amino acetic acid modified poly(vinyl chloride), MPVC, was obtained by chemical modification of PVC using glycine methyl ester. MPVC was used as a precursor to prepare some functionalized MPVC conjugates to be used in biomedical applications. MPVC-Cs
