Crosslinked, predominantly polypropylene-based compositions |
摘要 |
A crosslinked, predominantly polypropylene-based article comprises a silane-modified ethylene-based polyolefin, at least 50 percent by weight of a non silane-modified polypropylene, and a silane condensation catalyst. The article is moisture crosslinked to a sufficient degree that it possesses thermoset properties such that, when the article is heated to a temperature above the crystalline melting point of the non silane-modified polypropylene, it is softened but does not become liquid. The article preferably comprises a heat-shrinkable sleeve for a high-temperature transmission pipeline.
