Novel additives for accelerating radiation grafting of monomers to polymers in acid media.

摘要: Abstract Mineral acid and polyfunctional monomers in additive amounts (1% v/v) are shown to act synergistically enhancing radiation grafting yields for a typical system involving the copolymerization of styrene methanol polyolefins. Polyethylene polypropylene films have been used as representative backbone polymers with divinylbenzene trimethylol-propane triacrylate polyfunctionals current work. The effect dose rate on yield is reported. Grafting efficiency be enhanced presence both additives. A theory role additives proposed. synergistic also operates powder. Such an observation important applications these copolymers enzyme immobilization, heterogenization catalytically active homogeneous metal complexes, insolubilization analytical reagents art restoration.
