| Abstract: | Main factors affecting the graft modification of acrylic acid and methacrylic acid onto melt - blown polypropylene nonwovens initiated by benzoyl peroxide are studied. The relation between graft and reaction time, monomers and their con-centration , initiator concentration and leaving agent concentration are investigated. The structure and related performance of grafted nonwovens are analyzed. It is believed that wettability of nowovens is greatly improved by graft modification so as to meet the needs of medical filtering materials. |
