Endfunctional polymers possess significant industrial and scientific importance. Sulfonyl endgroups, such as tosyl and nosyl endfunctionalities, due their ease of substitution are highly desired for a variety of polymer structures. The sulfonylation of hydroxyl-terminated polyisobutylene (PIB-OH), a chemically and thermally

Three different surface modifications were conducted on the membranes of double-layer alginate/poly(L-lysine) microcapsules with tosyl chloride-activated poly(ethylene glycol), cyanuric chloride-activated poly(ethylene glycol) and tosyl chloride-activated poly(vinyl alcohol), separately. All these surface modifications strengthen the microcapsular membranes. Of the three surface-modified
