“…1 However, these additives are toxic, can leach out, and also affect the other additives needed to process polyolefins. On the other hand, hardly any successful research has gone into designing new plastics or effecting minor chemical modifications of polyolefins or similar polymers with attachment of sugar molecules [2][3][4][5][6] that can render the polymer molecule intrinsically biodegradable or bioassimilable, and convert these large volume polymers into environmentally benign materials.…”

Biodegradation of Styrene-Butadiene-Styrene Coploymer via Sugars Attached to the Polymer Chain

“…Although some aspects of functionalization of polybutadiene, such as synthesis of hydroxy-terminated polybutadiene and reaction of epoxidized cis-1,4-polybutadiene with p-aminodiphenylamine to obtain antioxidant properties [5][6][7], and functionalization of low molecular weight oligomers of poly(butadiene-co-acrylic acid) with sucrose [8,9] have been studied, there are no reports on functionalization of SBS with sugars. While there exists a significant body of literature on biodegradable plastics, there are hardly any reports on introducing biodegradability to synthetic elastomers like SBS.…”

Modification and characterization of poly(ethylene‐co‐vinyl alcohol) by glycosidation reaction

“…Although the polymer reaction method frequently results in glycopolymers having less regular structures because of incomplete reactions due to steric hindrance, the latter method is more simple and convenient than the former polymerization method, because the synthesis of sugar‐bearing monomers often requires tedious multistep reactions. Several studies described the incorporation of a sugar group onto the polymer backbone by a polymer analogous reaction 6, 9–12. For example, Bahulekar et al6 utilized this strategy to graft glucose and galactose onto polyacrylamides.…”

“…Galgali and coworkers succcessfully incorporated glucose, sucrose, and lactose onto poly(styrene‐maleic anhydride) copolymers using a polymer analogous reaction 10. Alvarez et al reported that sucrose was also grafted onto butadiene acrylic acid copolymers and poly(butadiene carboxylate) by the postmodification method 11. These works showed dramatic improvement in the rates of biodegradation of these polymers and/or cell compatibility 9–12…”
