Abstract:
The invention relates to the use of at least one prepolymer in a composition which includes: a matrix of at least one transparent semi-crystalline polyamide, and optionally at least one additive, for improving the crystallisation kinetics and reducing the warping of the composition while preserving or improving the transparency properties thereof as well as the mechanical properties thereof, in comparison with the same composition without a prepolymer, wherein the composition does not contain a nucleating agent.
