    Abstract: The invention relates to compositions consisting of A) 70 to 90 parts by weight of at least one polycarbonate, B) 10 to 30 parts by weight of at least one graft polymer containing a rubber-elastic particulate graft base, which contains diene, and containing a vinyl co(polymer) shell, C) 0 to 15 parts by weight of at least one additive, wherein the sum of the parts by weight of components A) and B) in the composition is normalized to 100, (i) characterized in that the rubber content from component B in the composition is at least 6 wt %, (ii) characterized in that the ratio K/S of the proportions by weight of rubber-elastic particulate graft base containing diene from component B) in the composition (═K) to the sum of free vinyl (co)polymer from component B), i.e., vinyl (co)polymer from component B) not covalently bonded to the rubber base in the graft polymer according to component B), and any free vinyl (co)polymer from component C) in the composition (═S) is at least 1.5, (iii) characterized in that the component A) contains at least one monomer unit selected from the group consisting of monomer units described by general formula (2), in which R4 represents H, linear or branched C1-C10 alkyl, preferably linear or branched C1-C6 alkyl, especially preferably linear or branched C1-C4 alkyl, exceedingly preferably H or C1 alkyl (methyl), and R5 represents linear or branched C1-C10 alkyl, preferably linear or branched C1-C6 alkyl, especially preferably linear or branched C1-C4 alkyl, exceedingly preferably C1 alkyl (methyl), and contains at least one monomer unit that is derived from a bis-(4-hydroxyphenyl) compound and that is bridged over the 1,1′ position of a cyclic hydrocarbon possibly substituted with heteroatoms, (iv) characterized in that the proportion (Acyc) of monomer units that are derived from bis-(4-hydroxyphenyl) compounds and that are bridged over the 1,1′ position of a cyclic hydrocarbon possibly substituted with heteroatoms, with respect to the sum of all monomer units derived from bisphenols in the component A), is in the range of 5 to 40 wt %, and (v) characterized in that the component A) has a relative solution viscosity of 1.20 to 1.28, determined according to DIN 51562 in methylene chloride. The invention further relates to the use of the compositions to produce components containing a plastic carrier and a multi-ply metal layer, and to molded bodies produced from the compositions.

    Abstract: Provided are a resin composition and a shaped product having excellent smoke generation properties and chemical resistance. The resin composition and the shaped product contain: a polyphenylene ether resin (I); a polypropylene resin (II); a hydrogenated block copolymer (III) that is a hydrogenated product of a block copolymer including a polymer block A and a polymer block B in which the total amount of vinyl bonding is 30-90%; and a phosphate ester compound (IV). Relative to 100 parts by mass, in total, of components (I) and (II), component (I) is 40-99 parts by mass, component (II) is 1-60 parts by mass, component (III) is 1-20 parts by mass, and component (IV) is 5-45 parts by mass. A partition ratio of component (IV) present in a fraction that dissolves in chloroform and component (IV) present in a fraction that dissolves in o-dichlorobenzene is 10 or more.
