IN-SITU-VERFAHREN ZUR ERZEUGUNG VON WASSER DURCH DEHYDRIERUNG VON METALLSALZHYDRATEN FÜR DIE FEUCHTIGKEITSVERNETZUNG VON POLYOLEFINEN

摘要

Compositions comprising a polymer resin comprising at least one copolymer with hydrolyzable groups, a water-generating metal salt hydrate, and a catalyst that comprises a metal atom and at least two ligands taken from the set alkyloxy and carboxylate are used to form articles that moisture-cure through in-situ generation of water via dehydration of the metal hydrate. The compositions are melt mixed to promote the dehydration and start the cure process during the mixing step. The curing compositions are formed and allowed to harden.
