Abstract
A metal/polymer laminate containing at least two metal layers and at least one core polymer layer laminated between two metal layers. The presence of a silane of formula (I) in the core polymer layer, on the surface of the metal layers or in a separate adhesive layer improves the delamination resistance of the metal/polymer laminate: R.sup.1.sub.yR.sup.2.sub.xSi(OR.sup.3).sub.4-x-y (I) wherein R.sup.2 is a C.sub.1-12-hydrocarbon group containing one or more atoms selected from the group consisting of N, S and O, 1 R.sup.3 is H--, C.sub.1-4-alkyl; R.sup.1 is a C.sub.1-12 alkyl group that may be ethylenically unsaturated; x is an integer of 1 to 3; and y is an integer of 0 to 2.
