    Abstract: The invention concerns a thermoplastic composition having high fluidity in the molten state, comprising at least: (a) one thermoplastic polymer matrix; (b) one oligomer selected from cyclic ester oligomers, ether oligomers and mixtures thereof, said oligomer having a degree of polymerization of between 2 and 25; and (c) one phenolic polymer; said compounds (b) and (c) being present in a weight ratio (c)/(b) varying from 0.25 to 6, and preferably from approximately 0.75 to 2.75. The invention also concerns a process for producing a composite article from such a composition by impregnating a reinforcement such as a fabric or a preform, the composite article obtained according to this process, and the use of an oligomer (b) in combination with at least one phenolic polymer (c), as a plasticizing additive in a thermoplastic polymer matrix.
