Definitions
- the present invention relates to the field of impact-reinforced thermoplastic compositions, in particular to compositions based on impact-reinforced polyamides using a block copolymer.
- thermoplastic compositions of the invention are useful in all fields of application of polyamides, particularly in fields requiring good thermomechanical behavior at low and high temperatures such as the automobile, sport, electrical insulation and protection against '' electrical or electronic equipment.
- the strategy consists in dispersing small particles in the thermoplastic matrix, which must then crystallize between the "walls" formed by these particles. This is called crystallization in a confined geometry.
- thermoplastics such as polyamides
