ABSTRACT:
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 (a) one modifying agent of the formula (I) or (II): ##EQU1## or ##SPC1##
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, l represents an integer corresponding to the valence of the Metal atom Me, and m and n each represent 0 or 1, and (b) 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.
