摘要: Ionotropic gelation is particularly appealing for the formation of hydrogels because it takes place under mild conditions, not thermoreversible, and does involve toxic chemicals. A well-known example alginate in presence calcium ions, which at base numerous applications involving this polymer. In study, alginate-derived oligosaccharides were converted into acrylamide- methacrylamide-type macromonomers two steps without resorting to protective group chemistry. They then copolymerized with 2-hydroxyethylmethacrylamide aqueous solution yield high molar mass biohybrid glycopolymers containing between 25 52% by oligosaccharide graft chains. comparative kinetic study showed that both reacted since early stages copolymerization, but mole fraction polymer was smaller than feed up 50–60% conversion increased markedly afterward. This effect sl...
