Abstract: A method for preparing an article includes at least a first component of a polyolefin in conjunction with a second component of a polymer made by ring-opening metathesis polymerisation of norbornene type monomers. The method includes pre-treating a surface of the first component, applying a ring-opening metathesis polymerisable mixture of norbornene type monomers and a catalyst to the surface, and curing the ring-opening metathesis polymerisable mixture in contact with the surface, wherein the ring-opening metathesis polymerisable mixture has a η1000 at 30° C. of more than 9 sec. Articles such as a pipe line field joint or a protective element for a concrete tunnel lining element can be made using the method.
