  • Laminates having a linear, acylated polyalkylenepolyamine intermediate binding layer and a method of preparation
    Patent number: 4132831
    Abstract: Novel laminates are prepared by a process comprising applying to a surface of a first substrate a binding amount of a linear, acylated polyalkylenepolyamine having a weight average molecular weight of at least about 10,000 as an intermediate binding layer and subsequently applying to the layer a surface of a second substrate. For example, polyethylene film is bonded to paper by an intermediate binding layer of poly(N-propionyl)ethylenimine.
