US 2026/0201157 A1 · CHROMIUM ACID ETCHING FREE METAL PLATING OF BLENDS OF ACRYLONITRILE-BUTADIENE-STYRENE AND POLAR POLYMER

Abstract

Thermoplastic compositions are described. A thermoplastic composition can include (a) a copolymer having units derived from a vinyl aromatic monomer and a vinyl nitrile monomer; (b) a rubber modified thermoplastic polymer; (c) a polar polymer that includes a carboxylic acid, an alcohol, or a combination thereof; and (d) optional processing additives. Metal plated articles that include the thermoplastic polymer composition are also described. The thermoplastic composition can have an improved yellowness index (YI) when compared with a similar composition that does not include the polar polymer.

Dependent claims

A thermoplastic polymer composition, comprising, based on the total weight of the thermoplastic polymer composition:

(a) 30 wt. % to 79 wt. % of a copolymer (A) comprising units derived from (i) a vinyl aromatic monomer and (ii) a vinyl nitrile monomer;
(b) 20 wt. % to 50 wt. % of a rubber modified thermoplastic polymer (B);
(c) 1 wt. % to 15 wt. % of a polar polymer (C) comprising a carboxylic acid, an alcohol, an amide, or a combination thereof, wherein the polar polymer (C) has a molecular weight from 5,000 g/mole to 25,000 g/mole;
and
(d) a melt-processing additive.
