Abstract:
1. A long-fiber-reinforced polyolefin structure of length ≧3 mm, which comprises a) from 0.1 to 50% by weight of at least one amorphous cycloolefin polymer, b) from 0.1 to 90% by weight of at least one polyolefin other than a), c) from 5.0 to 75% by weight of at least one reinforcing fiber, and d) up to 10.0% by weight of at least one additive which is different from components a)-c), wherein the percentages are based on the total composition and the long-fiber-reinforced polyolefin structure is made by a process which comprises I) inducting a fiber bundle through a flat die charged with a melt made from said amorphous cycloolefin polymer (a), said polyolefin other than a) (b) and, optionally, from said additive (d), II) conducting the immersed fiber bundle through a shaping die, III) cooling the fiber bundle, IV) postforming the fiber bundle, and V) cutting the fiber bundle perpendicular to its running direction to give the length of the structure or winding the fiber bundle up in the form of a continuous structure.
