<p>METHOD FOR THE PREPARATION OF A MODIFIED CRYSTALLINE PROPYLENE POLYMER A method for the preparation of a modified crystalline propylene polymer usable as a bonding material is disclosed, in which method a crystalline propylene polymer, for example, isotactic polypropylene and a propylene-ethylene block or random copolymer, is uniformly admixed with a modifying composition consisting of at least one organic peroxide, and a modifying agent consisting of ?-methacryloyloxypropyl-trimethoxysilane (Component (1)) and at lease one ethylenically unsaturated organic compound (Component (2)) selected from the compounds of the formulae (I) through (V): (I), (II), (III), (IV), and (V) wherein R1 through R9 respectively represent a hydrogen atom or methyl radical, Me represents a metal atom in 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 heating the above admixture at a temperature lower than the thermal decomposing point but not lower than the melting point of said crystalline propylene polymer.</p> |
