A polypropylene-based resin composition containing 0.001 to 10.0 parts by weight of benzoic acid with or without substituent(s) on its benzene ring and/or an acid anhydride of benzoic acid, with or without substituents on its benzene rings, to 100 parts by weight of a polypropylene-based resin is disclosed. The resin can generate mouldings with improved rigidity or transparency.

Hexa-n-propylbenzene undergoes the same anomalous type of FRIEDEL-CRAFTS reactions as hexaethyl and hexamethyl benzene. Acid chlorides and dicarboxylic anhydrides produce under elimination of an alkyl group the corresponding penta-n-propyl-phenyl ketones and penta-n-propyl-benzoyl carboxylic acids respectively. Reaction of the carbamylchloride-aluminiumchloride complex yields penta-n-propyl-benzamide
