摘要： The invention relates to improved thermoplastic compositions composed of one or more thermoplastics (component A), and a stabilized MBS core shell graft copolymer (component B) formed from a rubber-elastic core based on polybutadiene, and a hard graft shell.The stabilized MBS core shell graft copolymer (component B) contains a special stabilization formulation of at least one hindered phenol, a phosphite, an organic sulfide, and optionally a pH buffer system. The stabilized MBS core shell graft copolymer improves the impact strength and heat aging properties of thermoplastic compositions and polyacetal compositions.The shaped articles produced from the improved thermoplastic compositions are particularly distinguished by an excellent high-temperature impact strength and a good heat aging performance.
