Zusammenfassung: | Shaped articles or profiles of crosslinked polyolefins are produced using compsns. incorporating 60-90% polyolefin (I), 0.1-10% chemically bonded hydrolysable silane (II), 0-5% of a condensn. catalyst (III), where the mixt. also contains 0.1-5% water and 0-20% carrier (IV) for the water, e.g. a hydrated salt, and where cooling of the moulding or profile (to less than 100 deg.C) is effected under pressure (sufficient to suppress nucleation of steam). |
