✦ Synopsis

It is often pointed out that low water absorption and moisture permeability are drawbacks of polypropylene (PP). In this study, blending with an amorphous polymer was used to modify PP. For improving the properties of PP without any property depression, PP was blended with phenolic resin-Novolak type (PRN). PP/PRN blends were investigated by a contact angle test for surface properties to determine whether PP had hygroscopic characteristics due to the existence of PRN in the blends. In addition, for the sake of efficient investigation in this blend, chemical structure, mechanical measurement, thermal analysis, and morphological observations were also studied.
