There is provided a process for producing a modified polypropylene resin, which comprises the steps of mixing the following components (A) to (D), and reacting them with one another: (A) 100 parts by weight of a polypropylene resin, (B) 0.1 to 30 parts by weight of a compound having a bond or a functional group selected from the group consisting of a non-aromatic carbon-carbon multiple bond, an oxirane group and a derived carboxyl group, (C) 0.001 to 30 parts by weight of a compound having at least two functional groups reactive to a carboxyl group, and (D) 0.01 to 20 parts by weight of an organic peroxide having a decomposition temperature of from 50 to 1200C, at which temperature a half-life of the organic peroxide is 1 minute, wherein: (I) the component (C) contains a diamino compound represented by the following formula: wherein R1 and R2 may be the same or different and are each a hydrogen atom or an alkyl group, which group may be substituted with or unsubstituted with an inert group; and X is an alkylene group, which group may be substituted with or unsubstituted with an inert group, (II) the component (D) contains a compound having a structure represented by the following formula (2): (III) the steps comprise:(1) mixing components (A), (B) and (D), and reacting them with one another to obtain a reaction mixture, and (2) mixing the reaction mixture with a component (C), and reacting with each other, and (IV) the steps are carried out by melt-kneading in an extruder.
