Abstract
Diffusion of lithium, sodium and potassium chlorides from aqueous solu tions into polypropylene (PP) was studied. The changes in polarity of the PP surface were examined by measurement of contact angles and the depth distribution of the diffusing atoms was deter-mined using Ruther ford backscattering (RBS) and neutron depth-profiling (NDP). The sorpt ion of the chlorides results in increase in the surface polarity. Irre gular diffusion of LiCl into PP was observed.
