Claims13
A laminate comprising at least one first layer of at least one first metal and at least one further layer of a polymer composition (PC), wherein the polymer composition (PC) comprises the following components:
- (A) at least one polyamide, and
- (B) at least one copolymer obtainable by polymerizing at least the following components:
- (B1) at least one C2-C20-alkene and
- (B2) at least one C2-C18-alkenyl ester,
- wherein component (A) is obtainable by polymerizing caprolactam and optionally at least one of the components selected from the group consisting of:
- (A2) at least one C4-C40 diacid, and
- (A3) at least one C4-C20 diamine
- wherein the caprolactam is present in an amount of at least 35 wt % relative to component (A);
- and
- wherein component (B) is not a graft polymer, wherein the polymer composition (PC) comprises in the range from 2% to 30% by weight of component (B), based on the sum total of the percentages by weight of components (A) and (B).
