<p>A modified crystalline propylene polymer usable as a bonding material is prepared by uniformly admixing a crystalline propylene polymer, for example, isotactic polypropylene and propylene-ethylene block or random copolymer, with at least one modifying agent of the formula (I) or (II): (I) (II) wherein R represents a hydrogen atom or methyl radical, Me represents a Metal atom selected from Groups I, II, III and VIII in the Periodic Table, ? represents an integer corresponding to the valence of the Metal atom Me, and m and n each represent 0 or 1, and an organic peroxide, and heating the above admixture at a temperature not lower than the melting point and not higher than the thermal decomposing point of said crystalline propylene polymer.</p> |
