Abstract:
1. 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 either a carboxyl group or 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 120° C., at which temperature a half-life of the organic peroxide is 1 minute, wherein the compound of the component (C) is a diamino compound represented by the following formula, wherein R
