METHOD FOR PRODUCING A MULTILAYER STRUCTURE COMPRISING AN ADHESIVE COMPOSITION BASED ON AN AMYLACEOUS MATERIAL

A method for producing an article including a multilayer structure containing:-a first layer based on a metal or on an organic polymer;-and a second layer of an adhesive composition including by weight: a) from 15 to 40% of at least one amylaceous material; b) from 10 to 30% by weight of at least on...

Zusammenfassung:	A method for producing an article including a multilayer structure containing:-a first layer based on a metal or on an organic polymer;-and a second layer of an adhesive composition including by weight: a) from 15 to 40% of at least one amylaceous material; b) from 10 to 30% by weight of at least one plasticizer for this amylaceous material; c) from 10 to 35% of at least one nongrafted polypropylene; d) from 10 to 35% of at least one polypropylene grafted with a grafting monomer selected from unsaturated carboxylic acid anhydrides, unsaturated carboxylic acids, oxiranes and silanes; these percentages being defined relative to the sum of a, b, c and d; the first and second layers adhering to one another and the method including a step of bringing the adhesive composition into contact in the molten or softened state.
