“…The block copolymers would contain at least one hydroxyl group that could be used as a reactive site to produce the derivatives of the copolymers. The presence of hydroxyl groups in this type of copolymer was proved by the reaction of hydroxyl groups with diisocyanate 14…”

“…Recently, water‐soluble cellulose derivatives such as methyl cellulose and methyl hydroxypropyl cellulose were used as reducing agents and their block/graft copolymers with polyacrylonitrile and polyacrylamide were produced 13. Block copolymers such as poly(ethylene glycol)‐ b ‐polyacrylamide,13 polyacrylonitrile‐ b ‐poly(ethylene glycol) and polyacrylonitrile‐ b ‐polyoxypropylene,14 ketonic resin‐ b ‐polyacrylonitrile,15 and ketonic resin‐ b ‐polystyrene15 were successfully prepared with such redox polymerization systems. Compared to other methods of block copolymerization, this type of redox polymerization possesses a number of advantages such as applicability of ambient temperature, using water as the media, and easy preparation of block containing both blocks of vinyl and condensation monomers.…”

Polymerization and copolymerization of vinyl monomers such as acrylamide, acrylonitrile, vinyl acetate, and acrylic acid with a redox system of Ce(IV) and organic reducing agents containing hydroxy groups were studied. The reducing compounds were poly(ethylene glycol)s, halogen-containing polyols, and depolymerization products of poly(ethylene terephthalate). Copolymers of poly(ethylene glycol)s-b-polyacrylonitrile, poly(ethylene glycol)s-b-poly(acrylonitrile-co-vinyl acetate), poly(ethylene glycol)s-b-polyacrylamide, poly(ethylene glycol)s-b-poly(acrylamide-co-vinyl acetate), poly(1-chloromethyl ethylene glycol)-bpoly(acrylonitrile-co-vinyl acetate), and bis[poly-(ethylene glycol terephthalate)]-b-poly(acrylonitrile-co-vinyl acetate) were produced. The yield of acrylamide polymerization and the molecular weight of the copolymer increased considerably if about 4% vinyl acetate was added into the acrylamide monomer. However, the molecular weight of the copolymer was decreased when 4% vinyl acetate was added into the acrylonitrile monomer. Physical properties such as solubility, water absorption, resistance to UV light, and viscosities of the copolymers were studied and their possible uses are discussed.Dedicated to the 225 th anniversary of the Istanbul Technical University.

ZUSAMMENFASSUNG:Einige allgemeine Gesichtspunkte bei Vernetzungsreaktionen und Netzwerkstrukturen, die von linearen oder verzweigten Polymeren abgeleitet sind, werden diskutiert. Es wird eine kurze Ubersicht von neueren Publikationen auf diesem Gebiet gegeben. SUMMARY:Some general aspects of crosslinking reactions and network structures derived from linear or branched polymers are discussed. A brief survey of recent publications in this field is given.
