Hollow plastic object, particularly preform, resp. container, with a polymer barrier and manufacturing method thereof

Abstract

The invention relates to a hollow article with rigid walls (18 98), surrounding an enclosed space (19, . . . , 99) that occupies the interior of the hollow article (10, . . . , 90), made of a primary plastic base material (1) in which there is provided a secondary plastic material (2), consisting of a polymer, characterized in that this secondary polymer (2) is formed by a first component (A), being a cyclic diisocyanate as a cyclic compound, with an aromatic or optionally an aliphatic structure, and by at least one additional component (B), wherein this secondary plastic material (2) forms a barrier (12, . . . , 92) in the hollow article (10, . . . , 90), and method for producing thereof.
