Distribution of grafted poly(acrylic acid) in polyethylene film

摘要

AbstractThe morphology of acrylic acid‐grafted high‐density polyethylene film and the distribution of poly(acrylic acid) in grafted film are examined. The grafting was carried out in the acrylic acid aqueous solution with or without Mohr's salt (an inhibitor of homopolymerization) by preirradiation method. It has become clear that without Mohr's salt the grafted poly(acrylic acid) layer is formed on the surface of the film, while in the presence of Mohr's salt the grafting layer consisting both of poly(acrylic acid) and polyethylene is formed on the inside of the surf
