Study on the surface grafting of polypropylene fibers

Abstract In this article, the surfaces of polypropylene (PP) fibers were grafted by three different grafting systems, of which the initiators belonged to three different types, namely, the water‐soluble initiator, the redox initiator, and the oil‐soluble initiator, respectively. The grafted products were characterized by FTIR, and the grafting degrees were determined by acid–base titration. In comparison, it was found that the oil‐soluble initiator might be more suitable for the surface grafting modification of PP fibers. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 99: 734–737, 2006
