Abstract
Partially aromatic polyamide compositions containing an aliphatic polyamide and an alkaline earth metal carbonate have excellent adhesion to metal coatings which are produced by electroless and/or electrolytic plating. Also described is a process for the electroless and/or electrolytic coating of these compositions. The resulting articles are useful as parts in automotive and industrial applications.
Claims10
An article comprising, a composition comprising:
- (a) at least about 30 weight percent of a partially aromatic polyamide;
- (b) one or both of about 0.5 to about 15 weight percent of an aliphatic polyamide and/or about 0.5 to about 10 weight percent of a polymeric toughener;
- and
- (c) about 2 to about 20 weight percent of an alkaline earth metal carbonate;
- wherein said weight percents are based on the total weight of said composition, and provided that at least part of at least one surface of said composition is metal plated.
A process for the electroless plating and/or electroplating, with one or more metals, of a composition comprising at least about 30 weight percent of a partially aromatic polyamide, wherein the improvement comprises, said composition additionally comprises one or both of about 0.5 to about 15 weight percent of an aliphatic polyamide and/or about 0.5 to about 10 weight percent of a polymeric toughener, and about 2 to about 20 weight percent of an alkaline earth metal carbonate, and wherein said weight percents are based on the total weight of said composition.
