ABSTRACT:
The invention relates to chemically bonded laminated structures and their production from oriented polymeric laminae. The bonds between the contacting lamina are formed by chemical reaction across their interface involving constituent molecular chains of each laminae. Three methods have been found for producing the bonds: (a) bringing the surfaces of the lamina in intimate contact to within 10.degree. C. and 100.degree. C. below the melting temperature of the surfaces; (b) interposing a coupling agent for the polymer molecules of the intimately contacting surfaces of each member into their interface and heating the laminate to a temperature effective to cause reaction of the coupling agent with the molecules of each; and (c) interposing a catalyst to promote chemical reaction of the molecules of each laminae with the molecules of intimately contacting lamina into their interface and heating to a temperature effective to cause reaction.
Structures bonded may be from film sheets, strips or bands or they may be other configurations that have suitable surfaces for that intimate contact required.
