Abstract: Compositions comprising a polymer resin comprising at least one copolymer with hydrolysable 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.

Abstract: Rheology-modified, additive-containing ethylenic polymer compositions are prepared in a continuously operated extruder comprising first, second and third zones by a process comprising the steps of:



mixing in the second zone of the extruder an ethylenic polymer and a high-temperature decomposing peroxide at a temperature such that the half-life of the peroxide is equal to or greater than (≥) one minute and for a sufficient period of time to modify the rheology of the ethylenic polymer to produce a rheology-modified, melted ethylenic polymer for transfer to the third zone of the extruder; and
adding to the third zone one or more additives to the rheology-modified, melted ethylenic polymer to produce the rheology-modified, additive-containing ethylenic polymer.
