Photografting of acrylonitrile and methacrylic acid on polyethylene film under air atmosphere

摘要: Photografting of acrylonitrile (AN) and methacrylic acid (MAA) on low-density polyethylene film (thickness 70 μm), which benzophenone was coated earlier, investigated at 60°C in water medium under air atmosphere. In the case AN monomer, where grafted polymer formed predominantly, oxygen system promoted formation both homopolymer. With MAA homopolymer preferentially compared to polymer, accelerated by presence while suppressing that polymer. The peroxides photoirradiation seemed be a factor for polymerization It found additives such as hydrazine metallic ions (Fe2+, Cu2+, Ni2+) are useful enhancing photografting © 1993 John Wiley & Sons, Inc.
