아크릴산 그라프트 폴리프로필렌 부직포의 제조와 특성 = Transactions : Preparation and Characterization of Acrylic Acid Grafted Polypropylene Nonwoven Fabric

다국어 초록 (Multilingual Abstract)

The purpose of this study is in development of effective filter-type polymer adsorbent for removal of pollutants from wastewater by W irradiation graft polymerization. Photografting of acrylic acid (AA) on polypropylene (PP) non-woven fabric using benzophenone (BP) as a photosensitizer was investigated. Inhibition of homopolymerization was achieved by adding various concentrations of FeSO₄ . 7H₂O, CuSO₄·5H₂O and Mohr`s salt. As AA concentration was increased, the degree of grafting was increased as to a specific value and then decreased, and the effect of BP concentration showed the same tendency It was also found that the degree of grafting increased with reaction time and reaction temperature. Addition of the polyfunctional monomers and H₂SO₄ to the grafting system accelerated the photo-grafting. The melting temperature, molecular weight and breaking stress and breaking strain were decreased with the increase in the degree of grafting.
