Abstract
Abstract A terpolymer, consisting essentially of (a) a first component of ethylene, (b) a second component selected from an (1) unsaturated glycidyl ester of the following formula (I) and (2) an unsaturated glycidyl ether of the following formula (II), and (c) a third component selected from an alkyl acrylate, an alkyl methacrylate and vinyl acetate, is coated on one or both surfaces of a metal foil to make a laminate tape. O PARALLEL R-C-O-CH2-CH--CH2 (I) ANGLE O R-O-CH2-CH--CH2 (II) ANGLE O wherein R represents a hydrocarbon residue containing an ethylenically unsaturated bond.
