Biodegradable Aliphatic Polyester Ionomers

Abstract: A series of polyester-based ionomers containing dimethyl 5-sulfoisophthalate sodium salt (DMSI) with up to 5 mol-% diacid units was synthesized by two-step polycondensation. Furthermore a polylactic acid (PLA) was modified by introducing poly(ethylene-co-methacrylic acid) ionomers with different ion groups, such as Na, Li, and Zn, using the melt blending method. This review examines the effect of the ionic group on the dynamic mechanical properties, melt rheology, crystallization behavior, degradation behavior… Show more

“…In addition, the main feedstock, succinic acid, can be produced from fermentation of natural resources such as starch, which would further stimulate the development of PBS industry. However, the poor melt strength, bad tear resistance, relatively low biodegradation rate, and increasing brittleness during storage or service have restricted the extensive application of PBS [29,30].…”

“…Particular attention has been given to aliphatic polyesters due to their relatively easy synthesis, good biocompatibility and biodegradability, and acceptable overall pattern of properties [9][10][11][12][13]. Among them, poly(butylene succinate) (PBS) is nowadays one of the most appealing biodegradable polymer because it is fully sustainable, commercially available and exhibits a good balance of thermal and mechanical properties.…”

“…In order to surpass this shortcoming, some authors have introduced the ionomer approach into the field of bio-based polyesters [18,19]. Han et al [9,20] inserted ionic groups into the PBS main chain leading to an improved extensibility due to reduction of crystallinity as well as a noticeable modification in melt rheological properties due to the ionic interactions. PBS ionomers have been proposed as a solution for the brittleness and poor processability of other polymers.…”

“…A velocidade de biodegradação é maior para os poliésteres alifáticos com maior proporção em ácido glicólico, isto é, de menor cristalinidade, bem como para o polímero de menor MM. Um meio básico parece reduzir a velocidade de biodegradação dos poliésteres alifáticos em comparação com um meio ácido, devido ao facto de serem originados íons H + que reduzem o pH do meio [100] . O poliéster alifático mais importante nos dias de hoje é o PLA que, por degradação origina ácido láctico, um metabolito natural do corpo humano.…”
