Abstract: In the construction of a multilayer film in which an ethylene-based polymer layer is joined to one another layer by a polyurethane (PU) adhesive, the rate of cure and the degree of cure of the PU adhesive are accelerated by incorporating into the ethylene-based polymer layer a functional compound with active hydrogens, e.g., a polyol, and/or a cure catalyst, e.g., an amine, zinc or tin-based compound. The catalyst and reactive functionality may be present on the same molecule (e.g. alkoxylated amine or zinc ricinoleate). The catalyst and isocyanate reactive compound will migrate into the PU adhesive over time and accelerate the rate and promote the degree of PU adhesive cure, and the functional compound will promote the migration of the cure catalyst into the PU adhesive. In turn, this accelerated cure inhibits the migration of residual, monomeric amines from the PU adhesive into and through the ethylene-based polymer.

Abstract: An insulated glass sealant having the best characteristics of polysulfides and polyurethanes rather than the worst is made from a polysulfide-based polyurethane prepared by a one-step procedure wherein a randomly copolymeric hydroxyl-terminated polysulfide polyacetal is reacted with a polyisocyanate at a ratio of from about 1:1 to about 1:1.2 on an equivalents basis. The copolymeric hydroxyl-terminated polysulfide polyacetal is made by the condensation of formaldehyde with a mixture of a dithiodialkylene glycol and an aliphatic or cycloaliphatic diol.

Abstract: A thermoplastic elastomer is made by the reaction of an epoxy resin with a liquid mercapto-terminated polysulfide wherein the ratio of epoxy equivalents in the epoxy resin to mercapto equivalents is from about 0.6 to about 0.98, with the proviso that when the ratio is greater than about 0.95:1, the polysulfide is further reacted with an amount of a mono-epoxy compound sufficient to raise the ratio of total epoxy equivalents to mercapto equivalents to a maximum of 1:1. An elastomer having residual --SH groups is air-curable. The elastomer is useful as a hot melt sealant for insulated window units.
