Metal-plastic hybrid component

A polymer composition, comprising:

• a) from 50 to 99.7% by weight of at least one polymer having a molecular weight of 15,000 to 70,000 selected from the group consisting of polyamides, polyaryl ether ketones, and mixtures thereof, and
• b) from 0.3 to 20% by weight of one or more additives of the formula (I):
• MaM′bDcD′d (I)
• wherein
• M=[R3SiO1/2]
• M′=[R′R2SiO1/2]
• D=[R2SiO2/2],
• D′=[R′RSiO2/2]
• wherein each R is independently selected from the group consisting of H, alkyl moieties having from 1 to 12 C atoms and a phenyl moiety, and each R′ is independently a moiety having a structure of formula (II), formula (III) or formula (IV),
• wherein formula (II) is an alkylamino moiety
• wherein x=from 1 to 20 and R″ is selected from the group consisting of H and an alkyl moiety having from 1 to 12 C atoms,
• formula (III) is a (trialkoxysilyl)methylene moiety
• wherein R′″ is an alkyl moiety having from 1 to 4 C atoms,
• and formula (IV) is an epoxycyclohexylalkyl moiety
• wherein y=from 1 to 4,
• wherein the indices are
• a=from 0 to 2
• b=from 0 to 2
• c=from 10 to 500
• d=from 0 to 50
• a+b=2 and
• b+d≥2, and
• wherein the proportions of all constituents of the composition give a total of 100% by weight.
