摘要：
Various graft copolymers were obtained by ring-opening of succinic groups in styrene-isoprene block copolymers, modified with maleic anhydride, using reagents containing nucleophilic groups. Comb-like hydrophilic graft copolymers were prepared using polyethylene glycol-550-monomethyl ether or polyethylene glycol-2000-monomethyl ether. By interaction with hydroxypropyl methacrylate, ethanolamine or ethylene diamine, films with various extents of crosslinking were obtained. Copolymers were characterized by H-1-, C-13-NMR and i.r. spectra, GPC and LS analyses. The thermal behaviour of polyethylene glycol grafted copolymers was studied by DSC. Amphiphilic properties of the products were examined by investigation of their water uptake, contact angle, interfacial tension and Cu2+ transfer.
