Two-component polymer composite structures are described, such as a composite structure that includes a first polymer structure and a second polymer structure adhered to one another through interfacial adhesion provided by a semicrystalline random copolymer with 70-88 mole % propylene units and alpha olefin units having 2 or from 4 to 10 carbon atoms, the semicrystalline random copolymer having a heat of fusion of from 2 to 90 J/g and a crystallinity of from 2% to 65% of the crystallinity of isotatic polypropylene.
L'invention concerne des structures composites de polymères à deux constituants, telles qu'une structure composite qui contient une première structure de polymère et une deuxième structure de polymère, collées l'une à l'autre par adhérence interfaciale obtenue par un copolymère aléatoire semicristallin à 70-88 % en moles d'unités de propylène et à unités d'alpha-oléfine contenant 2 ou de 4 à 10 atomes de carbone, ce copolymère aléatoire semicristallin présentant une chaleur de fusion de 2 à 90 J/g et une cristallinité de 2 % à 65 % de la cristallinité d'un polypropylène isotactique.
