Abstract:  Melting points and heats of fusion of various polymers consisting of polypropylene grafted with polyacrylic acid, free from homopolymer and obtained under different conditions, have been examined. The melting point decreases on increasing the percentage of the initiator in the reaction of grafting, but is essentially independent of the amount of the grafted monomer at constant initiator/polypropylene ratio. This is related with the small density of branching, due to the grafting reaction which causes small variations of structure. The existence of a two-phase system has been demonstrated by electron microscope.
