Abstract
The relative efficiency of grafting of acrylic acid (AA) in the surfac e layer and in the bulk of preirradiated polypropylene fibers was stud ied by combining the ATR and transmission IR techniques. At graft perc entage from 41 to 98, the surface layer contains 2-3 times higher conc entration of the grafted chemical groups than the fiber bulk. At 140% of AA, the surface of the host polymer becomes screened by the grafted material.
