## Abstract The main place of solidβstate graft polymerization in polypropylene (PP) granules has been believed to be the amorphous region of PP. In this work, the solidβphase morphology of nascent spherical PP (NβPP) granules was found to be markedly changed by an annealing treatment. The crystall
## Abstract The grafting of poly(acrylic acid) to polypropylene was realized with supercritical CO~2~ as a substrate swelling agent and a monomer/initiator carrier. The effects of different supercritical CO~2~βassisted impregnation conditions on the substrate mass increment and grafting efficiency
